Null Peta: Doki♥ Nullnull Petapeta! Mizugi Darake no Onee-chan Taikai!

In the anime Null Peta: Doki♥ Nullnull Petapeta! Mizugi Darake no Onee-chan Taikai!, the genius inventor sisters Null and Peta find themselves thrust into a wildly chaotic and international pro-wrestling spectacle. The anime centers on their surreal struggle against formidable foreign alter-egos of themselves in a high-stakes, swimsuit-clad tournament.

The story humorously explores themes of identity, sibling rivalry, and outrageous competition as the duo navigates this bizarre event. With the added question of whether any alternate version of Peta possesses actual culinary skills and a referee seemingly incapable of controlling the madness, the anime promises a unique blend of over-the-top action and eccentric comedy focused on the bond between sisters.
