Tsukihi

The deity of the Avian, who looks absolutely nothing like them.

She used to occasionally leave her palace in order to visit Chaos.

Using Kuon's gifted shard of the fell star, she decided to leave for another universe, coincidentally the same one Kuon lead Lucius and Remilia, and the same one Astora and Talon ended up.

Prior to the story, she was one of the original hunters that opposed the Godslayer, along with Chaos, Blade, and The Last Man Standing. She was trained by Blade.

Appearance
She has a rather young appearance for her age (which I guess corresponds to her more emotional demeanor), preferring to wear clothes that make her look fancy, though she does wear that weird pin on her hair, guess she likes it.

Personality
Up until now, she seemingly behaves like an immature child.

She does, however, show fondness for Chaos, even calling him "brother" while she's called Etro a "witch". As such she wants to hear nothing about the legion and its advances, and she has a disdain for "humanity" (those born from Etro), believing they are getting what they deserve.

She's slowly started to forgive the events prior to the Black Legion's rampage, she decided she'd rather leave for another universe and experience other worlds to help with that process.

Abilities

 * Quintessential immortality (meaning by her very nature she cannot be killed by normal means)
 * Generation and control over fire (mastered fire magic)
 * Dimensional refraction (up to sixth refraction) (learned from Blade, who can do up to seventh refraction)

Trivia

 * The reason Excellion kept the name of the character he's using as the design is because in his words "it was too juicy", as it's a reference to fire, which is related to the mythical creature, the Phoenix. And he also liked the name too much.
 * Her nickname, given to her by her master, means "swordflash".
