Biology
Momo is a pink flying squirrel-like Onryo, where he has circular eyes and ears along with a cream-colored face, body hands and legs. He also has a pink flame-like tail at the back, where he moves it around constantly when in a happy mood.
He has a rather simplistic, yet demanding personality at times where he tends to speak in short sentences ending with Desu-nee (ですねぇ) as a verbal tic in Japanese, along as saying "Momo dayo! (モモだよ!) every time he appears. Momo is also known to like cheese.
When summoned with the YSP Watch, Momo will appear bigger in size, enough to carry several people on board and allowing him to be used as a method of flying transportation.
