Name: Ochikobore Mahoushi to Itan no Chikara Dropout Magician and Heretical Power 落ちこぼれ魔法師と異端の力 Raw Link: http://ncode.syosetu.com/n7399cv/ NU Link (if avaliable): N/A Why It Should Get Picked Up: For the Harem and Snusnu~ Description (if you can find one): The only country in the world, Leylia Kingdom. The true governing body of the country is The Holy Church. In the decades of absence of The Goddess, a title bestowed to a Holy Maiden possessing [Holy] Elemental, the ones in power are The Church's 7 Sages and their 13 Apostles. Half of the population are magicians and naturally social strata are determined by the family's magician's grade. The protagonist, Seiya Khrisna is an orphan, thus he's a clanless, earning him the lowest position in society and school. This treatment is not a mere label, since being clanless disabled him from early life education which in turn resulting in his low magical proficiency. One day, he and 3 other students were kidnapped by the rumored magician kidnappers. They were brought to their base in [Darkness Territory] which is basically the whole world beside Leylia's Kingdom territory, deemed unsafe for filled with Demonic Beasts. Seiya was singled out to be dissected but he awakened a power that erased the base and the surroundings entirely. That power is [Dark] Elemental, the power of heresy forbidden by The Holy Church. He gazed at nothingness around him, but then he found a girl surviving the erasure. Her name is Yua Aluna and somehow she knew his secret and withholding a secret of her own.
It's been a long time since I've seen a novel that has a strong vibe of "Kuh the darkness in my hand restraint thy self".
