Subaru appears to be a young and gorgeous woman with long blonde hair with pink sidelocks, ending with ringlets and blue eyes. She is always seen with both hers eyes closed, but sometimes her eyes are opened.
She wears a white frilly gown with pink lining, black gloves and a matching large white sun hat decorated with a large pink bow, giving her an image of a high-class lady.
Subaru is a calm, cheerful, elegant, and friendly person and is rarely seen serious or angry. She enjoys teasing Rokuro and Benio's relationship. She speaks in a Kyoto dialect.
There is a running gag in anime. Subaru is shown to be a very big eater, as she was able eat all ten cups of ramen, despite actually being on a diet.
Adashino Benio was former student of Subaru. In Chapter 14, Benio recalled Subaru encouraging her to work hard to be the next head of Adashino House. However, Subaru wanted Mayura to kill Benio for her if needed, possibly for Benio being the Taiyin. In anime, most of her lessons also have Dating Tips and Lessons too.
Mayura's first impression to Subaru is, that Subaru and her mother is similar.
After the match, Subaru forcefully take her as an apprentice. She trained Mayura in a Spartan style more harsh than Seigen.
Subaru first appeared on Episode 10 where she greets Rokuro and Benio in their house commenting that it needs a little more decorations and asking how was their marriage. Rokuro and Benio then begs Subaru to trains them to which she agreed just to be found out to be a Date Training rather than Exorcists Training they were asking for. As their date progress, Subaru was constantly seen teasing them especially if they failed to do what they're ask to and when a horde of Kegare appeared she demonstrate her powers by exorcising them with ease using her guns. She then later stayed at the Twin Star Exorcists' house so that she can continue with their training (Marriage Training).
She later had a Hide And Seek game with the Twin Star Exorcists with the condition that if they win she will train them which proves to hard because Subaru already anticipated all they're possible moves and when Rokuro and Benio fought with a Giant Kegare, she was shown watching with Tatara only to be found out that it was yet another familiar for the Subaru is really watching a movie in a parking grounds.
Subaru and Tatara reported their discovery which is the broken branch of the Abe No Mihashira and She later participated in the Heavenly Blue Earth Ritual in hopes of permanently closing the dragon spots, being the one of Six Guardian that will channel the spell and having Tatara to protect her area. But unfortunately, Subaru and the others were trapped when Kuranashi turned the Spell Ritual against them and was only freed when Sae returned to the Ama No Mihashira.
She is present when Mikage Tsuchimikado announced that he will be the acting Head Exorcists while Arima is missing and was later seen participating in finding Arima like the other Heavenly Commanders.
In Episode 33, Subaru and Tatara are still on the Magano trying to find Arima but only Kuranashi's lingering scent is what they found. At the Twelve Guardian's Meeting, when Tenma Unomiya comments on Miku Zeze's current age, Subaru was irritated saying that one even struck a nerve with her and when Mikage reported about the oracle saying Arima is dead she is one of the most shocked in the room but still tried not to panicked as seen when she still manage to calm Tatara who is about to throw a tantrum.
Subaru is seen with Sakura taking over Mayura's Job dealing with the impurities.
In the island tournament (Hadara Castle Games), she is matched up against Mayura and though they were meant to fight Subaru teased the latter by fondling her, to Mayura's dismay. Subaru told her not to be so nervous and tells her its alright to attack but Mayura refuses demanding for her to put armor on herself. The heavenly commander refuses and starts attacking repeating that its alright for her to attack her if she so wishes to, to which Mayura; after getting hit by her attacks; says that she'll end up killing her if she gets serious. This act was met with jeers from the crowd, particularly the Mitejima house who stated Mayura had no chance against their leader. Subaru asks Mayura why she was fighting anyway since her homeland had nothing to worry about but laughed after hearing the girl's reason was to keep her friends from being sad. She obliged Mayura's request to fight back and soon overwhelmed the young girl who realized her arrogance was what led to her defeat. Subaru declares aloud that she will take Mayura as her disciple and that she can still get even stronger. Subaru also quietly tells herself: 'It's possible that one day, I might have you kill that child in my place'.
