Lucien, a guy who has nothing but the desire to save his mother. To get strong enough, he makes a contract with the demon of L.u.s.t. And now, only by making a great harem, will he gain the power to protect those dear to him.

This is a prequel to the anime movie To Aru Majutsu no Kinsho Mokuroku – Endymion no Kiseki.

Just before the completion of the Academy City space elevator “Endymion”, the main characters Kamijou Touma and Index encounter a level 0 girl named Arisa. The Magicians are after Arisa, and they attack Academy City. A female leader named Shattoaura leads a unit from Academy City against the attack. Kamijou and Index learn from Stiyl that Arisa is key to a brewing war between the sides of Magic and Science. When science and magic cross paths, the story begins with Endymion as its stage!

In his previous life, the MC was a total degenerate—lazy, self-indulgent, and only skilled at gaming and skipping responsibilities. One day, he dies in a ironic accident.He wakes up in a magical world, reincarnated as Eryndor Sylvaren, the youngest prince of the Ethereal Elven Empire. The elves are a proud and noble race, and their royal family is bound by strict traditions of honor, discipline, and responsibility—none of which the MC has any experience with.Luckily, he receives the “Divine System of Degenerate Growth,” a system tailored to his flawed personality. He makes the same mistake of repeating his past life only to realise that this new life has so much in store for him. Mistakes have consequences for power.NOTE: This book is a slow paced action adventure story that explores a vast fantasy world. If you like weak to strong, harem growth, high stakes, dungeons and adventurers,with a compelling storyline you should give it a try.
