Our discord server: https://discord.gg/bd9aDdEeQK Without noticing it, a man called Bill passed away, but then he realized that his life wouldn't end that way and soon he was reborn as Billy in another world. Billy was already satisfied enough that he retained his memories, but the surprises didn't end there. He was born with a weird power that granted him the chance to convert mana into experience points and transmit it to all sorts of things. Things were looking pretty good until he noticed that he was born in an impoverished and rustic village that was facing their imminent extinction in the hands of creatures that he had never heard of before and other tribes that had all sorts of abilities. Before he could learn how even to crawl, Billy had to find a way to help his tribe. Otherwise, they will be annihilated before he can even become strong enough to stand. Billy's journey will be much different than he had imagined. Much farther away from Earth than he had originally thought, Billy will have to adapt to a new environment where his tribe is at the bottom of the food chain. Will he be able to grow up safely and try to change things for the better for his new family and friends? The story, all names, characters, and incidents portrayed in this production are fictitious.

A oreigaru or snafu/DxD crossover featuring our infamous loner Hikigaya Hachiman who for unknown reasons was suddenly ripped from his reality and dropped into this foreign world filled with danger in every corner. And he needs to find a a way to deal with his new overly attached and attention-seeking 'friends'.

Also don't forget to review and stuff, I want to know your thoughts on my story! And all chapters are between 2k - 4k words.

Alan Bennet was what you would call a regular teen. He had no redeeming qualities. Neither handsome nor ugly. Neither talented nor untalented. Neither fat nor slim. Neither good nor bad grades. Alan Bennet was always in the middle, and he was used to it.     Second of three siblings, he was used to being ignored the most. He got the less amount of gifts on Christmas or his own birthday. His parents had even forgotten to pick him up from school once, after which he began to walk back on his own.      To make things even worse he had, after two exhausting years, gathered enough courage to confess to his only friend. Of course, he was rejected.  "Why would I date someone who doesn't even try to better himself?"      Those words were played over and over on his mind as he walked the long way to his house. He didn't want to reach it, at least not so soon. He preferred to stay outside with nature and animals, which were the only two living things that seemed to pay any attention to him. The stinging words resounded in his head once more, but they were mixed with something akin to a truck's horn.  *HONK*     His sight, which had been lost looking at nothing, was suddenly filled with a white titan of 600 hp. That was the last thing he saw before his consciousness was lost. When he woke up the next time, everything would've changed.  *     For Convenience's Sake, you may just refer to this story as "iCOMA".  

While others are trying to control the mana within them, Vi, on the other hand, is controlling the huge pool of mana in the world he is in. As a level 1 player who can't level up, he resorts to other methods to become the strongest. Can't tame monsters and summon spiritual beings? No problem, he can use his own blood to create summons. Can't wield weapons made by metals and renowned blacksmiths? No problem, he can use his own bones as his weapons. Can't use elemental powers through mana? No problem, he can use his own shadow to cast magic. Can't execute enough physical power with his level 1 body? No problem, he can transform and bring out unparalleled strength. Can't use illusions and other mental attacks? No problem, he can do all of it with his hair. And thus, Vi becomes a king different from everyone. A king who without an army or kingdom, but a king who alone defeated everyone obstructing his path.
