Rikuto Aoshima Husbando

Rikuto Aoshima ((靑嶋 理久人) was the Blue Keeper, he was one of the five Dragon Keepers and was the leader of the Blue Battalion, until he was heavily injured by an unknown Executive and retired, causing Shōgo Aoshima to take up the mantle. He has shown to be caring as he raised Hibiki and Sesera even after he retired, and still cares about Shōgo despite being a "graduate" of the orphanage. However he seeming is a carefree person as he doesn't fuss over good vs. evil and claims it is enough to just one pick a thing you are good at and sticking with it.
