RE ZERO LIGHT NOVEL VOL 01 (C: 0-1-0)

Description

"Subaru Natsuki was just trying to get to the convenience store but wound up summoned to another world. He encounters the usual things - life-threatening situations, silver haired beauties, cat fairies - you know, normal stuff. All that would be bad enough, but he's also gained the most inconvenient magical ability of all - time travel, but he's got to die to use it. How do you repay someone who saved your life when all you can do is die?"
