Love is All!; ラブ上等!.
First year Hino Teppei of East High has a lifelong enemy.
His nickname is “The Demon of the West,” but his actual name is Onikubo…a second year whose goal in life is to tangle with East High students.
No matter how many times he gets called out, he’s so strong no one can make a dent…and yet, he only has eyes for cute things!
One day, Hino picks up Onikubo’s chick coin purse, and Onikubo thinks “that yellow nape of his makes me think of a chick”—and becomes attached to him!
Furthermore, he’s able to go from “I don’t hate you” to a kiss…?!
