It has been more than ten years since he was transported to another world. The protagonist Deris Fahrenheit, who has became a magician with special circumstances, was freely enjoying his life in this world. However, a girl appeared before him and asked him to make her his disciple. That girl seems to be a transported person――

It’s a story of him who becomes the girl’s teacher and trains her to achieve her revenge (?) in otherworld.

Although it was only a marriage of convenience, Amelie Ashford was the perfect wife in every aspect. She was intelligent, obedient, and well-respected. She was kind to everyone and devoted to her husband. And she was perfectly content to spend the rest of her life like that, even though she was constantly nagged about getting pregnant. That was until her husband entered their house with a mistress by his side and eventually demanded a divorce.“Very well,” Amelie said calmly, “I will divorce you.”Richard's eyes shone as he heard his wife utter these words. However, to his surprise, she was not done. “But don't be surprised when you get an invitation to my next wedding.”To everyone's shock, Amelie indeed got married again, and to a younger and, as it turned out, richer man!And she made sure that her ex-husband realized what it meant to lose the support of a woman like her._____

[You have been killed by the Hero of Light.]

[You have died.]

I had died at the hands of the main character in the novel I had read before.

But I got another chance. I regressed and returned to the time when I first entered this novel world.

Once again, I live in this novel world as an extra character.

Since I have experience and knowledge, especially my World System which had upgraded, I'll do what I want to do.

I will become stronger than the main character.
