He find he'd become a hamster.

The three sisters are now his owners! There's Himari, the kind and reliable eldest one; Futaba, the straight-laced middle one who's obsessed with health; and Miyu, the youngest one who's a sassy high schooler.

Kota, or rather ""Hamta,"" his new name as a pet, was as confused by the situation as he was pleased with all the pampering.

However, he noticed something. The sisters didn't seem to get along as well as they used to.

What happened during the past six years?

You'll need to use your tiny paws and big heart as well as you can to uncover the truth and help bring them back together!
