Odekake Kozame Creator Makes Bocchi the Rock! Crossover Comic
posted on by Ken Iikura-Gross
The world's cutest shark and Bocchilla united to hold sway at Japan's biggest anime convention this past weekend, to the delight of their fans, including a certain famous voice actress.

Odekake Kozame creator Penguin Box released a Bocchi the Rock! collaboration short comic on March 19. The four-page comic follows as the titular shark Kozame-chan explores the annual AnimeJapan event at Tokyo Big Sight. The shark encounters Hitori Goto, Ikuyo Kita, Ryo Yamada, and Nijika Ijichi from Bocchi the Rock! In true Goto fashion, she is shocked at Kozame-chans's social media presence and summons Bocchilla. Caught up in the moment, Kozame-chan also dons a Bocchilla outfit and the two “reign terror” on the anime event.

Hanazawa lamented on social media on March 22 that she wanted to meet Kozame-chan, after seeing posts from one of the meet-and-greets. Thankfully, she met the shark during the booth stage event and later shared photos and videos with Kozame-chan:
