Here are a few headcanons for Io:
- He has a habit of not eating, which explains why he’s thin
- His hair hides a secret!
- Io is recovering from being emo when he was a freshman, but it isn’t quite working
- Not much of a happy person(because he was emo “last year”)
- Only takes in water and milk
- Faints often
These are better headcanons than my others!
