As known as being called from another world. Since Mina wanted to come back earlier, she used around a month to save the world. Mina returned to her word peacefully and thinking of living a normal life. Mina opened her door, the first thing she saw was the devil.

"Ah, welcome back my slayer!"

Unexpectedly, Yoo Jeongyeon the devil followed her home. 

"Slayer~" Jeongyeon rushed to her and back hugging Mina. 

"Okay, I'm back." Mina said with an annoying tone. 

"Don't be so cold, I've waited for you all day." Jeongyeon said that while leaned forward to her ear and hand cupping her cheek. 

"You look small today too, that's cute." 

Mina's eyebrows narrowed and trying to escape from her. 'Jeongyeon really worth the name of a devil, how could I resist when she's so strong.'

"Stop touching me!" She's punching Jeongyeon with her elbow. Jeongyeon finally let go. 

"Oh that's hurt."
