Arukõru is born as a Gluttony Demon, and quickly became one of the most known partygoer of the Gluttony Planet. After reaching the level of Friste in her Multiverse (the one Akasen is in), she got more and more depressed, knowing the true reality of things. But getting a daughter helped her getting around some of her problems, and she hopes that the world can become a better place, filled with food and joy, obviously!
