Koutei Tenma (コウテイ・天魔) is a character in the Fanon-Novel-series, Battle Spirits REBOOT.

"Appear from the purple darkness! Magician who controls the graves! The Necromancer Yakumo!"


He is a boy with red eyes and light purple hair that has two strands going down to his chest. He wears a white v-neck under a pale yellow jacket that's black at the center, gray jeans, black socks, purple sneakers and 2 idential chokers with the bottom one having a gray stone attached.


He is a mysterious individual who doesn't talk anymore than he needs to and rarely shows any emotions to anybody, aside from a sly smirk from time to time. Despite this, he is shown to care about people and takes battle spirits seriously. He is also shown to be calm no matter what situation comes his way and is not above setting up traps in order to lure opponents into doing what he wants if he knows that it's the only or the most sure way to win. He also never backs down from a battle spirit challenge unless he has a perfectly good reason to and habitually twirls one of his hair strands when he's thinking.


He utilizes a purple deck focused on reviving and destroying spirits which combines both offensive and defensive strategies.
