May I Call You Aniki

is episode 26 of the Beelzebub anime.

Summary
Oga and Furuichi accept Kazuya as their student, after being praised on how legendary they are. Kazuya tries to copy Oga to become strong like him, even making identical lunch boxes. Due to the Teimo incident, Oga and Kunieda meet Kido, the teacher in charge of student life at Saint Ishiyama Academy. They receive a warning of expulsion, should they persist to cause trouble for the school. Meanwhile, Kunieda tries to learn from Azusa to be more open to men, but realises it to be impossible. In order to get Kazuya off his back, Oga pretends to teach the secret technique of electric shocks, and manages to convince Kazuya successfully. Kazuya hears news of Azusa being kidnapped by a bald man suspected to be a Teimo member, and tries to rescue her with his new "powers". After Kazuya fails to land any hits, Kunieda arrives and reveals the man to be an acquaintance of her temple, and the situation is resolved.

Trivia

 * Okuka is the name of the transit fare card used by Oga, Furuichi and Kazuya upon entering a train station.
 * En, Yolda, Izabella and Satura make a cameo appearance when Kunieda's grandfather's friend comes to Saint Ishiyama Academy. Their pose is reminiscent of one in chapter 81.
