100 Days!!

ひゃくにちかん!!

High school student Shuuto Sakaguchi eagerly anticipates three months of freedom when his parents leave for an overseas business trip. His plans are abruptly overturned upon returning home to find a five-year-old girl named Chiho Norita in his house. Chiho's mother, a colleague of Shuuto's parents, has also departed for work, leaving her daughter in his care without his prior consent.

Suddenly responsible for a young child, Shuuto is completely unprepared for the challenges of childcare. With no experience and no choice, he must navigate the daily trials of feeding, entertaining, and understanding his tiny new roommate. As the days pass, their initially awkward and problematic cohabitation slowly evolves into a shared daily routine.

Over the course of their hundred days together, Shuuto and Chiho's relationship gradually deepens. Through small moments and shared experiences, they begin to form an unexpected but strong bond, with Chiho becoming an integral part of Shuuto's life.
