Ijuin and an army of girls as his bodyguards under his control

When Ijuin first arrived at the academy and being introduced he started putting all the girls under his spell, "Je t'aime" (French for "I love you") including Tsukune's friends, Ms. Nekonome and Ruby. Ijuuin sees Kokoa who is looking for her bat, Kou, but when she met Ijuuin she believed him to be gross. Ijuin saw Kokoa to be a great victim. After Tsukune become suspicious about this and told Gin what the transfer student is doing, Ijuin putted Gin under his spell (acting like a puppy) leaving Tsukune to solve this problem all by himself. Ijuin thinks to himself about how he can control the whole school with his power of hypnosis, laughing aloud.

In the school auditoritum filled with girls, Ijuin is singing on the stage with Tsukune's friends as background singers. Tsukune arrives telling Ijuin to stop but is haulted by Ruby. Kokoa arrivies and tells Ijuin to stop singing as it annoys her. Ijuin tries to put Kokoa under his spell and imagines Kokoa in a wedding dress. Ijuin gives himself away when called Kokoa by "Kokoa-sama" knowing that's what Kou calls her. As Moka is able to move where Kokoa is to save her while being controlled by Ijuin, Tsukune tries to jump Ijuuin but missed and landed on Moka and Kokoa. Ijuin then realized that Tsukune removed Moka's rosario releasing Inner Moka seeing he's in be trouble now. As Ijuin tried to put the two vampires under his spell, Moka together with Kokoa countered attack with a double kick and defeated Ijuin. With that, Ijuin changes back into Kou and with his broken fang releases his spell of controlling all the girls then returning back as Kokoa's servant.


  • Charm: Ijuin is able to charm alot of girls when they first look at him.
  • Allure: Ijuin is able to use this ability to let peoples guards down when he says "Je t'aime". Anybody subjected to this ability will fall in love with him and see him as their master, fawning over him and obeying his every command as he charmed every female regardless of sexuality (minus Inner Moka) and straight male Ginei, gender and possibly sexuality do not matter. This ability is hinted to be lost at the end of episode 10 when his fang, which glitters whenever he uses the ability, breaks. However, it is unknown if his second fang can do the same, or if said fang can grow back, as this was the one and only episode arc for Kou. This ability is similar to when the succubus Kurumu uses allure on every male.
