Hyakuren no Haou to Seiyaku no Valkyria
I will rate this after I am done with other anime and stuff
I have yet to write this... because I am lazy or something
Yuuta has been transported... I guess back in time to an age of magic on earth. A tribal time when tribes basically endowed a warrior with powers and then went to war with each other or something. Yuuta has taken over as the Wolf Clan's patriarch. A position earned by being the best in the clan. While he is not good at fighting, physically fit, or that much smarter than your average high school student, he does have one thing going for him, he happened to figure out how to make his smartphone work. As such he has access to the thousands of years of human knowledge thousands of years before it was umm... knowledge.
