Shunsuke Makabe

Shunsuke Makabe is a sadistic lackey of Junji Handa who attempts to collect 2,000,000 yen from Masami to give to Handa as a token of congratulations for his engagement. When Masami is unable to provide this amount within the given deadline, Makabe increases the debt to 5,000,000 yen. (Source: Mousou Dairinin Wiki)
