天使　ももこ

An angel who came down from heaven on her own to study humans.

She's a gloriously upbeat and happy individual, who pays zero heed to the depressing and sad elements in life, and always wears a beaming smile on her face. Perhaps owing to this disposition of hers, she is quite a social butterfly with lots of friends.

Incidentally, her grades are just as bad as, or worse than, Ami's, and she cares even less about this than Ami does. However, it can be argued that she sees enabling a general atmosphere of happiness in the people around her as the most ideal raison d'etre for an angel.

It goes without saying that she too is wild about donuts.
