I finished this game on the 18th of December in 11 hours without any guides. (There aren't any yet lol)
I'll be referring to "Mora" and "Ehter". Just to clarify, left is Mora, right is Ehter.

Rich Man: Give gifts to any girls 100 times
You get money from dates. You can only give girls gifts they like, if the item has a star next to it, she likes it. See example below.








Night City Explorer: Visit every location
Self explanatory. I just played the game for a little and got this achievement fairly easy.
Possibly bugged, some people reported they can only find 10 out of 11 locations.


Cyber Expert: Use Cyber Tools 50 times
Cyber Tools are the gifts you can give a girl during a date. If you use them frequently, this achievement will pop after some time.


Crafting Master: Craft every Cyber Tool
To do this, you need to do commissions in your clinic to gain the right materials and craft all the items.


Let loose have fun: Get a girl drunk and date with her
Self explanatory. Give a girl a few drinks and date her.



Joyful date: Accumulate 40 joy in one date
Pretty sure that joy = energy
So collect 40 energy in one date.


Looser: Match 7 tokens without creating a super token
Do this before High Skill
For this you need the lowest possible luck. Match 7 tokens in a T shape (like High Skill) and hope it doesn't create a super token.

Lucky Man: Get a super token with a 3 token match
Upgrade your luck and this should happen at some point in a date.



High Skill: Create a super token by 7 tokens matched
To do this, you need to match 7 tokens in a T shape. Make sure your luck is maxed out so a super token appears.


Flirtation expert: Reach 5 hearts with every girl
Self explanatory. Date all girls successfully until you reach 5 hearts.



Trait Master: Max all traits
Earn Ehters to max out all your traits.



Famous Ripper Doc: Take 30 Commission Orders
Take commissions in your shop. Complete the maximum amount of 6 orders per day and you will be done in 5 days.


Drinkers: Get every girl drunk at least one time
Drunk in this case means: fill up a girl's entire "alcohol bar" at least once
To do this, you need 12 intoxication points, for example 3 drinks with a value of 4 intoxication

Moves Expert: Successfully complete a date with at least 16 moves remaining
Easiest with maxed out traits and on easy/ normal mode. Match as many move tokens as you can.


Ripperdoc Master: Earn 1500 or more Affection in a single move while on a date
This isn't very hard but it takes quite some time and luck.
Things to help with this:

• Maxed out traits
  
• High Harmony level
  
• Use girl's preferred token type
  
• Match 7 tokens if possible

Busy Man: Finish final night date with every girls within 4 hearts
I'm not sure with this one as it's worded a little weirdly but I assume that you need to finish the final night without ever failing a date. (If you fail, just Alt+F4 and retry)
For this you need to start a Night date when the girl has 4 hearts. Do this for all girls and you get the achievement. (Thanks Lounger, The Creator)

Night Hunter: Finish final night date with every girl in hard mode
Toggle hard mode by starting a new game and selecting "hard" as the difficulty. Be more strategic about dates (see Date Strategy below).


Challenger: Successfully finish 10 challenge dates
Toggle Challenge Mode by giving every "pantsu" to Himeko. Dates are more difficult so watch out.

Collector: Unlock every girl's collection
Lucky for us lazy people, there's a function to instantly complete a girl's collection. Simply save up enough Mora and click said button. (Or you can buy every gift for a girl)


Understanding: Read every story
After spending the final night date with a girl, look at her profile > story.



Information machine: Unlock every girl's preferences and details
Just ask questions until you know everything. More information in this guide:

Underground Boss: Earn 200.000 Ehters
You don't have to own 200.000 Ehters at once, what counts is your "lifetime income".
Earn Ehters by:

• Giving girls gifts
  
• Talking to girls
  
• Doing commissions in your shop

From having played HuniePop quite a bit I could just apply my usual strategy.
For this you need 6 items (I mostly use them in this order as well):

1. Mini Nuke
   
2. Health Tracker
   
3. Cyan Badge
   
4. Silver Badge
   
5. Purple Coin
   
6. Golden Coin

Start off the date by collecting 3 Energy (silver pill tokens).

• Give Mini Nuke

Collect more Energy by making 4 token matches

• Give Health Tracker

The goal is to get the Harmony and Energy level as high as possible.
Try to only make 4 or more token matches, Harmony and Energy matches. If not possible, match the girl's preferred tokens.
Use Cyan and Silver Badges to get rid of the void things if needed.
When you have enough Harmony and Energy or you have only 1 move left:

• Give Purple Coin first
  
• Then, give Golden Coin
