Krylya Mori is an Alatura of the fifth division. Fifth division Alaturae like him are known for being quite capable fighters.

As a fighter Alatura, he was eventually sent to fight for entertainment at the age of about 15. He quickly climbed the ranks, which caused the higher ranked fighters to believe he was a threat to them.

One of these high ranked fighters framed Krylya for murder. Mori's father forced him to plead guilty, and Krylya was promptly exiled from his own home; sent to die out in the decaying forests outside of the kingdom.

Having managed to survive the decaying forests in enough time to travel to a more habitable region, he had begun to collect flowers, finding them pretty. Soon, he found towns and cities that he had not previously known of, learning more and more about the world outside of his old kingdom. He eventually tried selling the flowers he had collected, which quickly managed to get him enough money to get a small cart which he stored and sold flowers in. Soon Krylya had built himself up to owning a full-blown flower shop.

Mori soon met Jasi at a cafe that Jasi was working at, quickly finding the man charming and even cute; practically falling head over heels at first sight. He soon became acquaintances with Jasi, eventually becoming his boyfriend.

He now lives a peaceful life, living with Jasi Suzuki... And the man's pet cat, of course.

Krylya often acts kind and optimistic, always trying to see the good in people and their actions even if there is none.

He usually wears a blank and thoughtless gaze, spacing out and getting distracted easily. He ends up getting lost in thought, even to the point of not responding while somebody is talking to him.

Despite his tendency to lack concentration, he's a good person and tries to be a shoulder to cry on and let people confide in him.
