There Was Something Money Couldn't Buy - "Kane de Kaenai Mono, Arimashita" (金で買えないもの、ありました)
After finally returning to school from his humiliating defeat, Himekawa uses his money to buy off various punks into kidnapping Baby Be'el so he can take revenge on Oga. Unfortunately, Oga and Furuichi see through nearly all of his tricks and beat up his henchmen. Eventually, Himekawa runs low on money after paying off all the various punks to deal with Oga, so he tries to take care of the man himself until he gets his "allowance" from his parents. But even then Oga simply beats him up without acknowledging him. Finally, during yet another scheme, Himekawa spots a gang of thugs that Oga beat up in the past planning to ambush him, and decides to take them out himself so he can lay claim to Oga on his own.
