Plot
Shimokawa better know as 'Good Night" Shimokawa is a leader of the second years, and the second person to be beaten by Oga (not including Akbaba) his title comes from his catch-phrase; "Good Night". Though being a second year, he can't even spell his own catch-phrase as seen when Furuichi picks up his note book Shimokawa writes it a "Good Nait".

He also has a crush on Tohoshinki member, Aoi Kunieda, and constantly asks her out on a date if he bested her in a fight but due to being one of the weakest characters in the series, he always loses.

As he is very weak, he is usually seen either beaten up or being made fun of. For example, Kanzaki called him a chump while at the same time adressing him as; "Good Morning".

Since moving to the Saint Ishiyama, and sharing a classroom with most of the major delinquents of Ishiyama High, he started spending more time with the MK5, and is considered by many a sixth, or honorary member.
