Seriousness deals with the amount of slacking off a Yo-kai does in battle. Note that in Yo-kai Watch 1, Seriousness was part of Attitude.
Yo-kai Watch 2
Yo-kai Watch 1
First part of Attitude, now known as Seriousness, deals with the yo-kai's aloofness in battle, particularly during auto-attacks when the player is not controlling them directly.
From the best to worst:
- Players can use the book A Serious Life to increase this part of the attitude by 1 level once per Yo-kai.
