沢菓 愛里
from Guardian Ninja Mamoru
Airi, a wealthy girl, is a classmate and friend of Mamoru and Yūna. She discourages any relationship between Yūna and Mamoru, because, according to her, childhood friends who become lovers are generally unsuccessful. However, this may be a ploy since she has feelings for Kagemori, whom she derisively calls 'Ahoru' ("Mamoron"). She occasionally gives Mamoru hints that she likes him, which he is oblivious to, and she vents her frustration by hitting Mamoru.
Guardian Ninja Mamoru
Kagemori Mamoru is a dowdy boy whose hair is disheveled and who wears thick glasses, but he is actually the son of a ninja family. They have protected their neighbors, the Konnyaku family, secretly for 400 years. Mamoru has personally protected their daughter, Konnyaku Yuuna, since they were in kindergarten. When Yuuna is in trouble, Mamoru puts on ninja suit and turns into a competent ninja to help her.
