- They won't believe they're someone else (as in, an actual character from another series), they'll just believe it's always been like that (so feel free to adjust their canon memories as you wish!). And although it's possible to make some adjustments, it'd be best if their personalities were kept as intact as possible.
- Whichever genre you choose doesn't necessarily have to match your character's personality! You could have magical girl!Doumeki or gunslinger!Sakura or whatever.
- Their clothes will change, if necessary.
- For other appearance alterations, you can abuse the springs event, mutations event, and aging/de-aging event.
- Your character could gain new abilities to fit the genre you chose! Just make sure to make a note about it somewhere in the journals. And if the abilities you need for them would have to affect other charas, or Kiseki itself, please comment here to make sure it's okay.
As usual, let me know if I'm forgetting anything, and feel free to ask any questions.
