"fishing ball"), sometimes written as tsuritama, is a Japanese anime television series that aired between 13 April 2012 and 28 June 2012.

[2] Yuki Sanada is a high school student who lives with his grandmother Kate, a woman whose career requires frequent relocation which prevents the boy from establishing any real friendships, much less the social skills necessary to initiate them.

Shortly after arriving at their home on the grandmother's most recently sanctioned work base, the island of Enoshima, a zealous transfer student named Haru— wielding a water gun and sporting a fish bowl atop his head— appears on their doorstep claiming to be an alien and that he will henceforth be living in the same house; the grandmother agrees to allow such if Haru simply meets one condition (which is undisclosed to the audience).

The two also meet a secluded young fisher, Natsuki Usami, nicknamed "The Fishing Prince" and an Indian man named Akira, who watches Haru from a distance with his duck Tapioca.
