The world I reincarnated into was a world that enabled you to use magic after having read a Grimoire.

And the Grimoire’s contents areーー you wouldn’t believe it- it’s 「Manga」.

This world’s people would take around a year to read a single Grimoire (Manga)

While for me, it would not take an hour, as it was「Manga」

Interpreting and understanding all kinds of Grimoires, the 6 year old me who became the World’s Strongest Master Mage, welcomed brides that were also 6 years old, and started living a carefree life……!!

Seria, a social outcast, has changed.
Seria Stern, the wicked woman who made everyone tremble with fear, was now calm.

In fact, she wasn’t just changed, she was a completely different person.

The moment she realized that she had possessed the body of the villain Seria, in a romance novel, she had a hunch about the future and decided to live low.

She would avoid kidnapping and harassing the original heroine, hence preventing her death by decapitation at the hands of Kalis, the second male lead.

In order to avoid that, she had to fix her bad relationship with Kalis and even healed his injured arm.

Thanks to that she got engaged with him, so it’s all worked out.
Finally, the original heroine returned, and her husband, Lesche, should be on good terms with her now.

“I’ve been waiting to escort her, so…”

Lesche asked, resolutely cutting off Kalis’ words.

“Miss Seria, it would be better for you to choose. With whom would you want to go with?”

Something was strange.
The original, wasn’t it perfectly fine?
