A Reincarnated Witch Spells Doom, Vol. 1

On her eighteenth birthday, shut-in Sena Shirai finally works up the courage to leave the comfort of her home-only to be hit by a truck! Luckily, she has a second chance at life as a witch in another world, but the only spells she can use are -explode- and -perish.- Unable to control her destructive power, Sena is shunned by the nearby villagers and doomed to live in isolation once again. But when a mysterious boy collapses at her doorstep on her (second) eighteenth birthday, will her fate finally turn around?
