i'm still reading, but there're some things i don't think are put there for no reason (unless Ratchet would put them in as false leads:
- Battler left family when his mother died / when his father married Kyrie,
- Kumosawa is known for not taking her duty seriously,
- we don't know Shannon's or Kanon's surname, maybe they aren't even humans looking at what happened to Kanon, they're treated on the same level as head of staff despite their young age,
- Maria had letter from "witch"
- doctor has been Kinzo's friend for decades, yet he wants to give all he has to family that doesn't give crap about him instead
