Zenryou na Furyou Koukousei no Nichijou

Samaritan High is infamous for its many delinquent students. At first glance, Kawai, Mori, and Tanikura fit the bad boy image—but wait... is that one of them rescuing a stray chihuahua? Whether it’s soothing crying children or spreading cheer around the neighborhood, these so-called bad boys are actually striving to do good! A wholesome slice-of-life comedy about a group of unexpectedly dependable "delinquents"!
