From book one: Being able to rip the soul out of a creature, store it in a precious gem, and use it to cast spells might make me the most powerful student at the Astra Argent Magical Academy. Only I can’t tell anybody about it. Because it's illegal, and they’ll kill me if they find out. But they need me whether they know it yet or not, so I’m going to capture a lot of souls and cast a lot of spells. This is gonna be a crazy semester. This is a monster-girl harem dark-magic academy story.

The last thing I expected was to gain the spells of the woman in my bed. Hell, I didn't even know magic existed until I'd cast a spell that morning. Then a beautiful teacher from a magical academy told me I could become the universe's most powerful mage. To get there, I need to become stronger. I need to ace all my examinations. And, most of all, I need to master the most potent spells. But I have to start somewhere.

Evan was just an average guy working as an EMT, but when he puts on an ancient dragon mask, he’s teleported to the magical world of Inati as a powerful black dragon. Now, he’ll have to save a beautiful priestess, rebuild a broken city, and fight a horde of zombie-like monsters led by an ancient demonic evil. If he wins, then the opportunity to build his powers, treasure horde, and empire will await him. If he loses, then his new friends will all suffer fates worse than death.

Duel your enemy and kill him. Take his assets, including his wives, as your own. Grow your estate and become the most powerful warrior mage this world has ever seen.

They call me mad, but I don’t see anything wrong with using science to create the perfect monster girl. They call me insane, but I just want to live my life with a harem of beautiful cat-girls, bear-girls, fox-girls, snake-girls, and...well, pretty much any type of monster girl. They call me a megalomaniac, but why wouldn’t any red blooded man want to make cute babies with all these beautiful monster girls? They call me evil, but they just don’t realize that I’d destroy anyone who tries to harm my monster girls.
