Maou Kyoudai. I have the hardest time convincing anyone to read this because, well, it's about cute little boys.
The Hero defeats the evil Demon King, however, he splits apart into 12 individual pieces, who then turn into small shotas. The Goddess then tells the Hero he must raise all 12 kids right in order to make sure they don't turn evil.
The entire series is just cute comfy interactions between all 12 of these brothers, Hero, and the world around them. It's like the shota version of Marshmallow, and the Son-fu manga amongst all the other Daughter-fu material that's out there.
