I'm pretty sure this covers almost everyone introduced in the main games between Ten Desires and Wily Beast and Weakest Creature.

• Hecatia is the only one missing, unless I somehow missed her
• Yuyuko isn't here since she wasn't actually introduced in Ten Desires
• Yoshiko is passed out behind the wall to the right of Seiga
• Mamizou is passed out right behind Mayumi

There's also the wolf and otter spirits outside the window, and a a drawing of the wolf spirit on the piece of paper. Can't seem to find the eagle spirit tho

The purple eagle spirit is under the otter.

Looks like Hecatia left them a note and some Strong_Zero.

So isn't that all the whole-numbered titles from the 2010s?
