Kakugo wo Kimete
Everyone always underestimates the cute and demure-acting Tetsu, until his unleashes his rage all over them. This son of a yakuza overlord has quite the bag of fighting tricks, and it looks like he's going to need all of them as a scheming pornographer and con artist tries to corner him by making him fall in love. Good story, but unlikely to be finished.
Kodomo wa Tomaranai
A spin-off and continuation of the series started in Mainichi Seiten where an all-male family of 2 moves in with an all-male family of 4. This story deals with Yuuta and Mayumi, both 16-year-old "stepbrothers" (not biologically connected) who share a bedroom. Mayumi's cheerfulness and pluck seems like a front to Yuuta who senses that there are some serious issues being blocked from resolution, and who resolves to find out what the problems are before this destroys Mayumi. The story also addresses the reality of being lovers in an overcrowded house (poor neighbours!) A lively and interesting tale with spirited, realistic characters.
