The Day I Became A God and Air are two anime produced by Key, a visual novel company known for Kanon, Clannad, Little Busters, and Angel Beats. Both anime are about a boy meeting a younger girl with a somewhat quirky personality and the summer they spend together. There are several other characters the main character meets who share a bit of their own stories with him as well. Watch either of these if you would like some sad moments (especially more present in Air), comedy (especially more present in The Day I Became A God), and decent animation.
