Beelzebub - Season 1 Episode 7 The Demon Lord makes his Park Debut

Oga's family coerce him into taking Beelzebub to the park so he can make his 'park debut'. Despite making a bad impression with the other mothers, Oga meets a girl named Aoi who is looking after her little brother, Kouta. Aoi tries to help Oga make his park debut which, partly due to the appearance of Alaindelon, doesn't reap much success. The general antics convince the other mothers to call over a police officer, who starts badmouthing both Oga and Aoi. Before Aoi can lose her temper, Oga throws him into a trash can, with Aoi coming off impressed. After Oga leaves, it is revealed Aoi's true identity is that of Aoi Kunieda, leader of the Red Tails gang and one of the Tōhōshinki.
