Infinite Dark Age

Signed a contract with darkness and became a dark contractor, with the skill 'Dark Summoning'. From now on, I can learn whatever I want to learn? Want to learn sword skills? It's okay, summon Raven, Dance of Broken Wings, and Exile's Edge will teach you which move you want to learn. Is it amazing to be able to do magic? Summon the dark leader Syndra, and dark magic will kill you! Game characters boring? Then let's have some second dimension. Want to learn ninjutsu? Summon Tsunade and Sister Terumi Mei. Want time abilities? Okay, summon the evil third sister. Want to learn space magic? It's even simpler, Yue-chan is calling you. . This novel and its characters are purely fictitious.
