クロノクロック

Rei Sawatari is the heir to a corporate empire, but his most valuable inheritance is his grandfather's pocket watch, which lets him rewind time by five minutes. Instead of saving the world, he uses it for small, everyday problems. Things get busier when he gets involved with several girls whose lives he starts to change. Purple software's Chrono Clock is a romantic comedy with a light time-travel twist.

Meet Sawatari Rei, heir to a corporate empire, whose most valuable inheritance isn't stock but his grandfather's pocket watch. Within it lies a curious power: the ability to rewind time by five minutes, an ability he can use infinitely, though mastering it proves tricky. While world-saving feats could be possible, Rei initially leverages this power for daily excitement—specifically, risk-free romantic reconnaissance. He confesses to one cute girl after another, then rewinds time to gauge their interest without consequence. But one ordinary school day ends in horror when a girl falls from the roof. Using his watch, Rei jumps back and discovers the victim, the shy but brilliant first-year Suzuki Miu, caught mid-confession with his best friend just moments before. Deeply impressed by the determination he lacks—confessing without a safety net—Rei impulsively decides to help Miu succeed in her next confession. This decision sparks a bizarre three-way dynamic, complicating Rei's own ongoing mission to confess to the girls on his list. For Sawatari Rei and his time-altering watch, this is only the beginning.
