18 Unlimited Data: Unlocked by reading all of the Emails


19. thx!（≧∀≦ﾒ: Unlocked by reading all of the novel parts

20. Endless: Start a new game after getting any ending

There are 3 Main ending, which are
"Genocide"

("feed" Clara on the sixth day, then "feed" Chio or Kazu) This ending is consistent if you pick Saeko's side every chance throughout the game, main choices would be telling her you enjoyed your time as supervisor and flirting with her. Although you should be doing that anyway because she's perfect.

"Suicide"

("feed" Chio on the sixth day, express dissatisfaction to Saeko in following conversation and then "feed" Kazu on the seventh.) the main difference between "Suicide" and "Atonement" is choosing to go back to the draw early on the 7th Night.

"Atonement"

("feed" Chio on the sixth day, this will cause Clara to die too. then in the following talk with Saeko on the beach, Tell her you "It was the worst" Then when Saeko says "So who cares? I can do what I want!" tell her no. Continue forward to the seventh day, "feed" Akari.
*this will also get you the Treat achievement.* Saeko will cry. During the night that follows, refuse to go back to the draw early. Then talk to her about the 3 topics you can, followed by asking "do you like anyone?" then, continue forward, you should get the the part where you crush Saeko in your hand however this time.. you don't. congrats! you got the "Atonement" ending!

This is the achievement that takes the most effort for sure, hence the whole section to remove bloat.
To clarify, you don't need to get everything in a single run in Dictionary menu you can press the "switch" button to view everything you've unlocked across saves.

World is Mine: Complete all the entries in the Dictionary


To get this wonderful achievement you must fill out the Dictionary I will list all of the items inside it and how they are earned



Charm:

Unlock Condition: Finish the prologue

Cookie:

Unlock Condition: "Ask what food Saeko likes during a conversation on the first night."

Camera:

Unlock Condition: "Explore Saeko's past memories during a conversation on the second night."

Knit Cap

Unlock Condition: "Find the third choice during a conversation on the third night."
(this requires you to refuse the first 2 earrings and flirt with Saeko by telling her she doesn't need earrings because she's cute without them, which is very true)

Jewelry Box:

Unlock Condition: "Complete Chapter 1" (There are two of these- as you can pick between 2 sets of earrings during at the end of Chapter 1)

Figurine:

Unlock Condition: "Talk about monster movies during a conversation on the fourth or fifth night." " you need to be on Night 5: S and I did the following to get it.. "What is it?" - "What do you think?" "Yea." "I was in fantasy world, do you think I'd be the villain?" "Yes" "Sorry" "A little" "Wow.." would you want to see it? "Yes" "Yeah" "Yeah" she'll then offer to watch something on the TV. BOOM, dinosour"

Sunglasses:

Unlock Condition: "**Try** to flirt with Saeko during a conversation on the fourth or fifth night."
(this can be done by doing the following commented by DizzyNPeas "Kill Kina on day 4 or 5, and say that you want to be reborn into a handsome guy. The rest of the dialog should be self-explanatory from there"

Concealer:

Unlock Condition: "Show interest in makeup during a conversation on the fourth or fifth night."

Seashell:

Unlock Condition: "Complete Chapter 2"

Hand Mirror:

Unlock Condition: "Complete the seventh night."

Broken Seashell:

Unlock Condition: "Complete Chapter 2"

Hand Mirror (Shattered):

Unlock Condition: "Complete the seventh night."

Hand Mirror (Turned)

Unlock Condition: "Complete the seventh night." (this mirror is gained during the "Atonement" route I believe. "Cosmic.horror" adds (feeding Chio on Day 6 to unlock the option to say "It was the worst." on Night 6 at the ocean, but then on Night 7 take the option to leave Saeko alone and return to the drawer early. This is the Suicide achievement route. As I fed cake to Akari and no one died on Day 7 I'm certain that Kazu is irrelevant to getting it.)

You must get all variants during your playthrough(s) to get the World is Mine achievement. however you will only be able to see one of either at any given time.
