So in this guide you need to get know the basics and terms of fighting games.
You can find the terminology here in this link: https://glossary.infil.net/index.html

You can also learn the basics of the game with link:
https://gtm.steamproxy.vip/app/411370/discussions/0/361787186436310558/

But for short i will be using fighting game terminology for the inputs:










So for movement we will be using the numpad notation [glossary.infil.net] and for the attacking we will be representing it with A, B , C and D.

• A being Weak attack
  
• B being Medium attack
  
• C being Heavy attack
  
• D being Shield

For short each number represents the direction the character moves, this is to pull combos. So for example if the guide says to do a 214D then that means it is a shield bunker[glossary.infil.net] you can also check the command list in game for the different attacks each character has. Or more in-depth here[wiki.gbl.gg].

PS: the inputs only apply when the player(you) is in the left side while the opponent is to the right side of the screen. Meaning that you have to mirror the inputs if you switch sides.

These 4 achievements are basic and simple to do, just follow the description of the achievements. If you have a hard time beating each stage you can set the CPU Difficulty to easiest (but for Perish, ye who dreams of the untold you need to beat the highest difficulty), the Damage level to Highest which increases how much damage you inflict to your opponent and Win count to 1 to end the stage much quicker.

Hologram Summer Replay

-Clear ARCADE mode.
Clear one game of ARCADE mode on all 9 stages. Best done with the highest difficulty so that you can get both achievements.

Perish, ye who dreams of the untold

-Clear ARCADE mode with the highest difficulty setting.
Just spam and hope you can win, You can still continue the playing the same stage even when you lose by simply pressing the TAB key when the continue timer shows up and choosing the same character you played as in the character select screen. Warning don't change character or else you will go back to the start of stage 1.

Nobody told me the lore is THIS big!

-Clear all characters' ARCADE mode.
This one is pretty simple, just get the ending for each character. Except for 2 characters which have a second ending.Being Neco-Arc and Riesbyfe as joke endings.

Entertain Me (HIDDEN)

-Meet Archetype in ARCADE mode.
For this achievement you have to play 4 stages with any character perfectly before stage 8, meaning that you cannot get hit once for the duration of the stage. The easiest way to do that is set the CPU Diff to easiest, Damage level to Highest and the win count to 1 to end the each stage in just 1 round. Because if you set it to 2 or 3 wins then you will need to not get hit during those 2nd or 3rd rounds or else it the entire stage will not count as a perfect stage. You will know once this shows up after Stage 7.

For this section it is about the any character achievements. This means that any character can be used to unlocked these achievements. Please note that most of them can only be unlocked by playing ARCADE MODE, VERSUS(PLAYER VS CPU), AND NETWORK MODE. If these achievements are tricky for you then you can play TRAINING MODE to practice but it will not unlock the achievements. (Except for Keep going at it til I'm satisfied).


Keep going at it til I'm satisfied

-Stayed in TRAINING mode for 15 minutes consecutively
Just Play TRAINING MODE for 15 minutes.

It's not my fault that I'm too strong!

-Chose and played all 3 styles of a character.
Just play all Moon styles using one character (Full moon, Crescent Moon and
Half Moon)

It's nothing!

-Performed ground recovery.
When an enemy finishes a combo or you get thrown, you can recover by quickly tapping 4 or 6 to immediately recover.


I've read this

-Performed EX guard.
Guards are done by pressing the back key which is 4 or if your in the other side 6, which will causes your character to guard when attacked which is normally blue. But it you time it properly you can do an ex guard which is gold.


I saw through this!

-Performed EX Shield.
Just like EX guards except using the shield button D.


Here we go!

-Performed Shield Cancel with an attack.
Basically you have to block an attack with a EX shield then counter attack which cancels the shield and counters the opponent.


Corporal Punishment!

-Performed Shield Bunker.
Perform 214D using Crescent or Full moon style.


You're an eyesore

-Performed Shield Counter.
Just like shield bunkers except instead of 214D it's a successful shield and then 236D on full moon while on half moon if you manage to successfully land a shield it automatically Shield Counters. Crescent moon does not have a Shield Counter.


Get out of my way!

-Finished a combo with a Reverse Beat.
Reverse beats can be done by timing an attack in reverse meaning instead of starting from ABC you start from CBA.


Charge-up!

-Charged more than 100% worth of gauge in a single round.
Use Full moon style and press ABC all at the same time.


Did you enjoy?

-Won a round with an Arc Drive.
Arc Dives can only be activated when you magic circuit gauge reaches MAX (The meter in the bottom). So in order to do this you need get your opponent to half or 1/3 their health then once you have your magic circuit gauge reaches MAX perform a left half circle or 41236C which activates you Arc Drive. This can be tricky so a recommend practicing in TRAINING MODE.


Let me devour you completely…!

-Won a round with an Another Arc Drive.
The same as Did you enjoy? but instead with Another Arc Drive, in order to activate Another Arc Drive you have once again build the Gauge to max but once its full press ABC all at the same time to activate BLOOD HEAT then just do the same input as before.


This is HOW you do(kill) things

-Activated Last Arc.
For Last Arc you have perform a BLOOD HEAT and then perform an EX shield which automatically activates Last Arc Mode. PS: Some character require you to perform the EX shield mid air like Arcueid or Len. So I recommend looking at their command list in the pause menu.


Let's enjoy this fight to the last second!(HIDDEN)

-Performed a combo with over 100 hits.
This one is very tricky but the one that worked for me is by using Crescent Moon Neko Arc Chaos and performing a shield bunker 214D and the quickly follow it up with a 623C. Best done on ARCADE MODE on easiest difficulty, because on stage one the CPU is less active than the Versus CPU. You will also need to push the opponent into the corner to make it easier to pull off, take note if you miss the combo then doing it again will not work anymore meaning you have go back to the main menu and retry.


Bountiful Nights

-Played in all stages.
Just play the game and set the stages to random, eventually you will get all the stages since some stages are not included in the stage selection.

For Section it is about the Character Specific Achievements. Meaning that they are tied to specific characters. If you don't understand some of the descriptions of some of these achievements then look into their command list and use TRAINING MODE to Practice. Also if you have a hard time pulling them off on VERSUS (PLAYER VS CPU) OR ARCADE then set the the CPU level to easiest. Again most of them can only be done ARCADE, VERSUS(PLAYER VS CPU) and NETWORK MODE.


Set!

-Fired the pistol over 30 times in a single round while using Sion.
Use Sion Eltnam and spam 236A which fires a single bullet you have 13 rounds before reloading so just spam it until you get it. Also if the opponents dies before you manage to get 30 rounds then you have go start again. I recommend setting damage level to lowest so that they can tank your shots.


18-part Dissections

-Landed "How About I Play With You For a Bit?" successfully on either Tohno Shiki or Nanaya Shiki, while using Arcueid.
Best done while doing This is HOW you do(kill) things achievement since it just needs you to land Arcuied's Last arch BLOOD HEAT Mid air EX - Shield on either Tohno Shiki or Nanaya Shiki.


What you're lacking is CURRY!

-Landed "Seventh Holy Scripture" successfully as a counter-hit while using Ciel.
This is Another tricky one since you need to perform a counter-hit using Ciel's Arch drive 41236C which can be tricky when against a CPU player.


All of yours shall belong to me

-Absorbed over 100% worth of Magic Circuit off the opponent in a single round while using Tohno Akiha.
For this you need to use Tohno Akiha Full or Crescent moon and perform Scorch the beast 22A which spawns a red puddle on the ground. When the opponent steps on it their Magic Circuit drains, you need drain 100% of it. Also don't spam it just wait for it to fade out and then do it again until you get the achievement. Best done by setting damage level to lowest so that they won't die quickly.


I'm counting on you~♪

-Swapped the characters before the start of a round while using Hisui&Kohaku.
Just swap to from Hisui to Kohaku as soon as the introduction ends by inputting 22D.


It's not like I like to make mistakes

Landed "Fake Reality Marble: Twirling Hisui World" successfully while using Hisui.
Use Hisui's Last Arch by landing a ground EX - Shield while on BLOOD HEAT.


After this tea, let's have a reeeeaaaaaaally long chat, shall we?(HIDDEN)

Listened in to the full plot of the "Grand Scheme to Take Over the Tohno's" while using Kohaku.
This is the Last Hidden Achievement and its really easy, all you have to do is let Kohaku Crouch 2 and wait for the three dialog's that she will random say. This is heavily RNG. Best strat is by Doing this on Training mode and change the opponent to Kohaku and set them to crouch then just sit back and relax while waiting for the achievement to Pop.

I'll have you take responsibility for killing me, okay

-Divided Arcueid into "Seventeen Dissections" while using Tohno Shiki.
Use Tohno Shiki's Another Arch Drive against Arcueid using BLOOD HEAT 41236C.


I have trained in Kung-fu for this!

-Landed 2 EX-Edges in a single combo while using Miyako.
This is one very tricky since you need time it properly or else it will miss. Basically here an example using an Elbow Strike 236C and timing it with Darting Arrow 214C. Note that Miyako's Full moon style is different than here Crescent moon style which I used here.


Cutcutcutcutcutcutcutcutcutcuuuuuuuutttttttt!

-Activated "Night On the Blood Liar(Unzanity)" thrice in a single round while using Warachia.
Perform Warachia's Arch Drive 41236C Three times in a single round. Best to set the Damage level to Lowest.


Genes of the Beasts

-Accumulated a total of 666 normal hits over the course of the game using Nrvnqsr Chaos.
Just set the damage level to lowest and spam living daylights of the CPU while using Nrvnqsr Chaos.

I am… thirsty…!

-Sucked over 2000hp from the opponent in a single round while using Sion TATARI.
Use Sion TATARI's Arch Dive 41236C to suck blood from the opponent. You need to close your opponent in order to work. Again set the damage level to lowest for the CPU to tank it.


Praise… the maginificent Crimson Moon…!

-Activated "Pluto die Schwester" twice in a single round using while Red Arcueid.
Activate Red Arcueid Arch Drive twice 41236C.


Resistance is futile

-Set a total of 15 counts of both "Scorch the Beast" and "Scorch the Gallopping Beast" added up while using Akiha Vermilion.
Not sure how I got this achievement, I just remembered spamming 22C can't remember what style of moon I was using. But some say to set the timer to not infinite and play it on VERSUS(Player VS CPU) while using Half moon Akiha Vermilion spamming 22C. Note you don't need to use Ex - Edge like what is shown in the example.


Phantastic Starry Omega Mecha-Hisui

-Used the chainsaw, saber, harisen, burning widget and shotgun in a single round while using Mech Hisui.
This one made me confused, as the shotgun wasn't an actual shotgun at all. But anyways here's what you need to do. Choose Crescent moon Mech Hisui and input the following C 2C 8B 82C 8214A.

Ran out of space in the First part LMAO.

Kickin' through!

-Landed "Flashing Sprint: Six Hares" twice in a single combo while using Nanaya Shiki.
Okay this one on the other hand is super hard since it needs proper timing and the opponent can block your attacks, all you have to do is to build your magic circuit to 200% or Max then stun lock the opponent into the corner and then do Two 623C Ex-edges and hope you can land both of them to count as a combo.


You liarrrr!!!

-Landed "I'm Angry, You know!" on either Tohno Shiki or Nanaya Shiki, while using Satsuki.
Use Satsuki's Arch Drive 41236C on either Tohno Shiki or Nanaya Shiki.


Reduced Sugar

-Landed "Cream Puff Dream REM" on White Len, while using Len.
Use Len's Last Arch Mid air EX- shield on White Len.


I'm not pulling no punches~

-Used "Repeat Magic" twice in a single round while using Aozaki Aoko.
Repeat Magic is only available by using Crescent moon style of Aozaki Aoko and performing any command and then pressing 22D which activates Repeat Magic which consumes 150% of your magic circuit.


Don't lump me in together with those clowns!

-Changed form into a cat while using White Len.
22D to turn into "a cat is fine too".


KishiMAX

-Activated Ex-Edge five times in a single round while using Kishima Kouma.
For this one you just have to do five Ex-Edges as Kishima Kouma. Ex-Edges require Magic Circuit so use Full moon Kishima Kouma when doing this.


My fists can deal five ton, er no, two tons of force

-Dealt over 7000 damage in a combo while using Riesbyfe.
This one is long, For my strat I set the damage level to the highest, CPU level to the lowest and the win count to 3. Basically we need choose Neco Arc Chaos as the opponent and we need choose Crescent moon Riesbyfe since her BLOOD HEAT deals enough damage in a combo to reach 7k and in order to build up magic circuit to Max we need to have a balance between you and the CPU, since the only way to get magic circuit with Crescent moon is to get hit or hit to the opponent, so we need to play about two rounds to have enough Magic circuit but not enough that it activates Max mode and on the last round we need activate BLOOD HEAT and input 236C while Neco Arc Chaos in the corner which deals enough damage. there are many different ways to do this but this is the one a found most consistent.


Lightning!

-Used "Secret Coat of Arms: Thunder Isolation" and charged over 20 lightning stocks in a single round while using Roa.
Use Crescent Moon Roa input 22A or 22B which charges the lightning once it reached 9 it automatically releases it. Do it 3 times


Pure Brute Force

-Never even jumped a single time in a round while using Powered Ciel.
Do I really have to explain this?

Raw, medium or well-done?

-Landed "Crimson Lord: Hair Cage" in total close proximity distance while using School Uniform Akiha.
Activate Tohno Akiha School Uniform's Arch Drive 41236C in close range.


Don't worry, it's painful

-Landed "Mystic Eyes of Death Perception Seven Worlds End" at close range while using Ryougi Shiki.
Activate Ryougi Shiki's Another Arch Drive BLOODHEAT 41236C in close range.


Dream combination ♪

-Activated "Multi-Weapon Service" 10 times in a single round while using Koha&Mech.
Just spam 22A since its the quickest to activate.


Dear Earth, I have returned to Steam…

-Spawned over 20 necoarcs in a single round. Necoarc wars?
Spam 421A which Spawns a bunch of Neco Arc's.


About time you get me a special ending cutscene god

Hold 236 and approach the opponent.


You will die if you just stay there, worthless thing (master)

-Attacked your Necoarc partner over 10 times in a single round while using Neco&Mech.
As Mech Hisui just keep attacking your Neco Arc.
