💭 Recommended Personas and Playstyles

✾ The class president of 3rd year, class 2, who tries to take care of the new transfer student.
✾ They must be an alien! A detective(?) who uncovers the transfer student's identity with Oh Young-jin.
✾ I wish the apocalypse would just come... A student with a sad backstory.

This is the last youth high school life simulator with non-humans (or rather, it's closer to a single-character game...).
I love the 'hara-guro' (black-hearted) non-human characters so much~~ I wonder if their identity is alien or... they spill their secrets so easily early on?!
Can't stop the AI... but it doesn't affect the gameplay, so please play comfortably 💦

I actually intended to submit this for a competition, but due to work, I couldn't make the deadline 🥹 Although it's late, I hope you enjoy it.
Thank you for playing 🙇‍♂️
