OVA 4

"Bang, Who is Too Overbearing" (強引すぎるバング, Gōin-sugiru Bang) is the fifth OVA of the One-Punch Man anime series.

Summary
After the events of Episode 7, Bang begins to spy on Saitama and Genos to gauge their abilities. Hopeful that his Water Stream Rock Smashing Fist martial arts is stronger, and that proving so will coerce Saitama and Genos to study under him, Bang invites Saitama and Genos to his dojo under the pretense of giving them free meat. Soon, Bang challenges Saitama to a variety of games, including card-based memory games and rock-paper-scissors, with Bang winning almost every time. During one rock-paper-scissors match, an enraged Saitama nearly crushes Bang with a hammer, who is then forced to admit that Saitama is truly powerful. He does note, however, that the rock-paper-scissors game was the most excited he had ever seen Saitama be, and offers Saitama to join his dojo. Saitama refuses. *This OVA is half as long as a regular episode.
