Kagaku na Yatsura ( Urusei Yatsura )

Deciding on a high school club can be a real headache, especially when you're caught in the middle of a rivalry between cyborgs and part-dog girls. That’s exactly the pickle Haruki Komaba finds himself in. On one side, there's Airi Kuze, a genius in mechanical science who has a crush on Haruki. On the other, we have Touko Hizuki, a half-dog, half-girl who excels in chemical science and also has her eyes set on him. The twist? Haruki accidentally promised to join both clubs, and now he’s stuck in a fierce tug-of-war for his loyalty—and maybe even his heart, if Airi has her way! To make matters even more chaotic, Touko's older sister, Ayana, who has a rather inappropriate interest in her younger sibling's affairs, decides to throw her own wild ideas into the mix. With all this drama unfolding, Haruki is going to have a tough time picking a club. If the girls don’t end up tearing each other apart first, that is! Also included in this volume is a one-shot titled "Hirotte Kudasai," adding even more fun to the mix.
