Time Stop Hero Vol. 2 (manga)

The Final Countdown

Kuzuno Sekai has been transported to another world where he has the ability to press pause, stopping time itself. However, the timer staring him in the face remains a mystery-when it hits zero, will he return to Earth, or simply die? He's got time to spare to ponder that (and undress freeze-framed young ladies), but the clock is running out for his latest quest: clearing out a dangerous level chock-full of goblins!
