サカモトデイズ

Taro Sakamoto was the most feared hitman alive until the day he fell in love, retired from the business, and opened a convenience store with his wife Aoi. His former protégé Shin Asakura, a mind-reading esper, works the counter beside him and their daughter Hana, but the underworld refuses to accept the retirement: former colleagues and contractors keep arriving with old grudges to settle.
