Don't fret! Your application has potential, but it's not all the way there yet. Before a full judgement can be made, we'd like to see the following changes made to your application as it exists now:

▢ For Kosuzu, the wikipedia link provided offers some personality components that aren't mentioned in the app, namely her confidence in herself ("She thinks she knows better than most other people...") and her gullible cowardice ("She develops a temporary fear of snakes after hearing a rumor that they can eat a human whole, and gets worked up over a horror story she hears from a pair of children, even after dismissing it as illogical."). Please expand on these traits as they would definitely help to round out her character and would come up in game!
▢ Also, the wikipedia link explains that Kosuzu still doesn't know how she feels about youkai, and that part of her growth as a character seems to be parsing out her opinion on the subject. However, your app states that she believes that youkai and humans can exist together peacefully and that her optimism leads her to trust them. Is this an issue of canon point, something you'd like to debate or can it be explained somehow? Fandom wiki links aren't always accurate, so it never hurts to ask for player opinion on the content they hold! This would also relate to a different aspect of her personality, so it's important to discuss.

Please respond with the corrections or response within 48 hours. Also, feel free to ask for clarification on any points.
