But, in a place where he was supposed to lose his life, he met Lunaère, a self-proclaimed misanthropic immortal girl. He was saved by her, who then decided to train him ’till he could at least protect himself.「Master, I think… I’ve become strong enough.」「It’s Not enough! Erm, outside of this dungeon is a dangerous place you know!」「Seriously!? More dangerous than this place…」This is the story of Kanata who was trained by his master, who easily succumbed to loneliness, till he became the greatest hero of legend, and yet was unaware of it.

[You have entered the dungeon at Gwachun Station’s 1st Exit.] When former high school student Kang Woojin finds himself returned back to Earth after being forcibly summoned to a foreign planet for 20 years, he soon finds that Earth is not the same, normal place as he once remembered it to be.

“….Krische-sama, are you not afraid of killing people?”

“……? No. After all, it doesn’t hurt Krische.”

Although gifted with the talent to do anything with ease, the girl lacked empathy.

In her world, there is only loss and profit. No goodwill, no love.

Inhumanly recognizing cold, mathematical logic as everything, she looks at everything in the world through calculating lens.

Return given profit with profit, loss with loss.

The girl was undoubtedly pure, yet undeniably abnormal—

Her favorite things are cooking, food, and being pampered.

Her specialty is mu*der.

—- This is the story of a slightly unhinged girl being surrounded by kind and loving people, and her journey to find happiness.
