Amachi

A true ladies' man, Amachi is the perfect gentleman, with a face to match. He is Manaka's rival for Tojo's affections, although he does not pose too much of a threat (It's apparent that she prefers Manaka). Like Okusa, Amachi has herds of girls flocking to him, and he seems to have a compulsive necessity in helping women in need. After meeting staunch resistance to his approaches on Tojo, Amachi gives up his horde of girls as a sign of devotion to Tojo, but later returns to them after news breaks out that Tojo is not going with Manaka or him to the final school festival. Amachi once challenged Manaka to a swimming race, (which he won of course) but Tojo dived into the water to save Manaka from drowning from exhaustion, despite the fact she could not swim. After seeing Tojo in her swimsuit, He had a nosebleed (comically) that was so bad, that Manaka had to walk her home instead of him. He also managed to recognize Tojo even with her hair braided and glasses on. Found @ Wikipedia
