Kagaku na Yatsura

Kagaku na Yatsura is a provocative, science-themed manga defined by its eccentric humor and frequent tentacle-driven antics. The story centers on Komaba Haruki, an ordinary high school boy whose daily life is anything but normal. His routine is constantly upended by his two highly unusual female companions, Hizuki Ayana and Kuze Airi, both of whom possess extraordinary physical traits born from bizarre scientific experimentation. Ayana is a unique human-canine hybrid, possessing the characteristics of half-dog genetics, while Airi is a half-cyborg whose body has been heavily augmented with advanced mechanical components. Together, these two eccentric girls form an unpredictable duo whose unconventional natures serve as the catalyst for endless chaos. Rather than enjoying a peaceful adolescence, Haruki finds himself perpetually dragged into compromising and wildly suggestive situations orchestrated by their bizarre abilities and lack of conventional boundaries. As he navigates the relentless ecchi troubles sparked by Ayana and Airi, Haruki must somehow survive the absurd consequences of living alongside friends who blur the line between cutting-edge science and unapologetic perversion.
