Missing Mom: Exiles herself from the Mirror Capital after receiving a prophetic vision that she will cause the destruction of the city. This vision actually concerned her future daughter, who shares the same name.
All of the Other Reindeer: As Myoue, he was an outcast due to his reality-warping abilities. As Inari, he is gossiped about because many members of Shrine disapprove of Inari bringing in an outsider, Koto, as his protege. He's also hiding his identity.
Being God Is Hard: Inari lacks his brother's dedication to their godly duties and while he never explicitly says it's hard, he does bemoan that it eventually began to feel pointless, particularly once humans appeared.
Captain Obvious Reveal: Inari is the first Myoue. It's hardly a secret when the siblings have already have suspicions that Koto is their younger sister and Inari shares many of Myoue's facial features and his unmistakable voice actor.
Commissar Cap: Regarded as being one of the most skilled members of The Shrine - with a hat to prove it!
Cool Sword: His katana, which is red and gold with embellished knuckle-guards around the hilt. Later doubles as a Cool Key after using it to possess Koto and destroy the Mirror Capital.
Death Seeker: His desire to pass on his responsibilities to his children and finally disappear is the driving force of the series.
Heroic Self-Deprecation: Flat out tells Koto that while he eventually came around to truly loving his family, he was never able to love himself. Indeed, his belief that his own existence is worthless is so strong that the entire story revolves around his complex plan to transfer his powers of creation to his children and be erased by God. It takes a stern talking to and a few slaps from his wife and daughter to finally come around.
No Celebrities Were Harmed: Myoue is loosely based on a real Japanese Buddhist monk with the same name who lived in seclusion on the mountain of Kozanji, outside the capital of Kyoto. His temple is also used as reference for the family's home.
Parental Abandonment: When Lady Koto has to leave Mirror Capital, he joins her - leaving behind his three children.
Physical God: Quite literally, in that he is one of God's two sons, tasked with balancing the universe. He loses this power by the end of the series, though.
Poor Communication Kills: Inari makes such a huge mess by never explaining to Koto how the Aratama shouldn't be used that he decides to go for broke by resetting the entire universe. He planned on speeding up the destruction of Mirror Capital by manipulating Koto in hopes that Myoue will use the beads and fix everything.
Youre like a child. You dont know how to control yourself. Everything you do is overly extravagant. Youre free, selfish, uninhibited. Self-centered. A cold-hearted monster. Yet, you know how to demand attention. A proud man, who cant bear to be alone.
Sole Survivor: Not for lack of trying. His parents were killed in a fire, and although he attempted suicide, he survived.
Uncanny Family Resemblance: Starts to look an awful lot like his adoptive father when he grows up. One theory for this is that, when Myoue passed his prayer beads down to Yakushimaru, there was also a transfer of DNA, making the two related by blood and therefore influencing Yakushimaru's looks.
