Canon
Ryuji, who commonly goes by Bon, and Izumo met when they attended Cram School at True Cross Academy, so they could learn how to become exorcists, and had bragged their childhood friends into it with them. Izumo and Bon didn't talk to each other during or after class, as they both get to their small groups of friends who they have known since they were children in their home cities. Until P.E. when Izumo heard Bon say that he'll beat Satan, which causes Izumo to snigger at Bon's impossible goal and says her thoughts about it outload while he was standing in front of a Reaper that attacks him when Izumo's harsh words got to him; but Rin Okumura manages to save Bon from the grog-like demon while Izumo watches them yell at each other before they joined the rest of the class.

After a Naberius attacks Izumo and her friend, Noriko Paku, at the abounded Boy's Dorm during their Training Camp there, before Bon and his friends rush into the room to see what had happened to them, the event troubled Izumo as she wasn't able to protect her friend and wasn't able to fully recite the requested scripter while Bon did very well to recite his. Due to his memorizing skills that his friends prize him for, but a upset Izumo didn't think that it was impressive and told Bon so before they began to fight with each other, that got the whole class in trouble as no exorcist fights alone and they needed to learn that.

Once Yukio left the class the dwell on the thought in a locked room, for their own protection, Bon and Izumo began to fight with each other again, as they blame one another for getting into trouble, while an unhappy Rin is sat between the two and asked them to stop fighting when he wouldn't take it anymore. Just before the lights died out and the demon from yesterday attacks. After Shiemi Moriyama had her Greenman familiar create a barrier to protect them, but it would disappear once Shiemi's strength gives out, Bon subjects that they use the Naberius's killing verse even though they don't know what it is and Izumo warns Bon that the demon would go after him out the plant-made barrier is down. Bon knew that Izumo is right but they needed to do something to get rid of the demon, until Rin manages to find the breaker box, as he and Konekomaru Miwa recite the whole bible that the verse is in. As the barrier went down and the demon had its way towards Bon, Izumo summons her familiars and gets them to bey her again before sending them to fight the Naberius before it reaches Bon. After the demon was killed, the attacked that revealed to be a test to see how they would handle that kind of situation while working as a team, with their teachers cleverly hidden to observe encase they needed to jump in. Izumo believed that she didn't do well in it while Bon and the others were able to use teamwork throughout the test, even though she came to Bon's aid at the last minute, but in the end they all passed it.

Their next Training Camp has them camping in the woods, where they'll go into the woods at night while the demons are at their strongest, Bon, Izumo and the rest of their class were tasked to find and bring back demon possessed stone lanterns, on their own. Izumo is bring back hers with help from her familiars, while Bon relied on the fellow classmates he ran into as they brought it back to camp together. Before the Demon King of Earth, Amaimon, attacks the camp in order to fight Rin. Izumo watches Bon and the others go to face Amaimon in order to save Shiemi, as Izumo thinks that Bon and his friend are crazy for charging up to a Demon King and that is why she remained in the protective circle like they were told to do, but still kept an eye out for their return. As Bon and the others were making their way back and just before they stepped into the circle, Amaimon catches up to them and targets Bon to lure in the demon's main target, which turned out to be Rin as Bon, Izumo and the rest of their classmates learn that he is the son of Satan. As Rin is put on trial Yukio explains Rin's brief story to them, Bon was angry at Rin for keeping that secret and couldn't understand why Izumo would sit next to Rin on the train ride to Kyoto.

The Inn they were assigned to stay at is owned by Bon's family where Izumo meets his mother and witnesses him being scolded by her about his choice of hair style. Bon and Izumo didn't spent time together during their stay due to their chores and duties, until after Rin lashes out at Bon for fighting with his father to which Bon later informs Izumo and their classmates of as they ask him what had happened.
