Her Bulter is a Demon Lord

Yuka was always bullied by Her family, Other schoolgirls,... Everyone. She was desperate. She wanted to die. But... Yuka summoned a Demon Lord, accidentally. She got 3 wish from Demon Lord. Would that made Yuka happy.... Or unfortunate for Her? P/S: My English sometimes isn't very well. I hope you all sympathy for me. Thank you very very much ^^. Progress: 3 chaper or more/week I will try!!!
