Saishuu Shiken Kujira

Kuonji lives in a town where supernatural occurrences are a normal part of life, often taking the form of people and objects brought to life by some unknown force. His daily interactions are filled with unusual characters, including Nina, who wears striped panties, and Sacchan, a cat enthusiast, as well as Allen, an extraterrestrial being. Kuonji's friendships with these individuals often lead to awkward and comedic situations, particularly when they're joined by other girls who are frequently scantily dressed. The town's bizarre atmosphere is a familiar backdrop for Kuonji's daily life.
