SANBE KEI

Senri Nakajou's twin brother was his everything, the one who protected him from their abusive father, the one whose pain he felt as his own. That is, until the day thirteen years ago when Senri's entire family was murdered before his eyes. He couldn't have cared less about his parents, but without his brother, his world ended. Ever since, finding the killer and making him pay has been Senri's only goal...and now-finally-he's caught a glimpse of a clue...!

Despite being in elementary school, it falls on his shoulders to care for his little sister Nagisa, who never stops asking when their mother will make one of her infrequent visits home. One day when she stops by, their mother takes them to an amusement park, only to give Minato some cash and leave them on the Ferris wheel. However, as they reach the top of the ride, lightning strikes their car— but what Minato finds when he awakens is not the grim tragedy he expected...
