I Said I'm the End, So Are You Eldolon?!

What would happen if the Thirteen Flame-Chasers came to the Elysian Realm of the present civilization? A spin-off of my previous book. The protagonist, Nolan, brings the Thirteen Flame-Chasers to the present civilization, fifty thousand years later, to save the world once more. There’s Aolian, the female captain, and the protagonist during the eras of Qianyu Academy and St. Freya. They’ll all become girls, since it’s a girls’ school, after all. If you don’t like gender-bending yuri, you can skip this. The protagonist can be male or female. The only heroines are Elysia and Mobius. There’s no angst, so enjoy without worry. None of those regrets will happen. This book ends with the Second Eruption. The story after that continues in the new book.
