Fat kitty died, killed by a lightning strike while stealing a chicken leg! And then, the kitty was reborn into a rich family in the 80s, which, having had nine grandsons, longed for a granddaughter and instantly made her the most adored one in the family! She was so happy with her life, being pampered by grandma, adored by parents, and protected by big brothers. Of course, it would have been even better if that big bad wolf hadn't cast covetous eyes on her.

A world filled with heroes with superpowers. A world attacked by calamity fiends. A modern world filled with wonders and dangers.
