Current Arc

Like all of Mikan's friends Ruka is sad about Mikan's absence and feels that Gakuen Alice is not the same without her. He wrote a letter to her in chapter 140. Along with Mikan's other friends Ruka has given Mikan a fairytale book for Christmas to cheer her up and give her hope. His book is called the Star Money. His message to her says,"The girl in the story [The Star Money] is just like you, Sakura."

During the Christmas party, he, like everyone else, is saddened that Mikan really couldn't come to the party and sees Natsume leave to go look for her. He later finds Natsume laying in the snow and asks if he's going somewhere again. Ruka is thrilled that Natsume and Mikan were able to see each other and says Christmas is amazing. He then catches Natsume coughing up blood and says that he's known about it for a long time. Ruka asks Natsume not to hide his pain, but let him be his supporter and that he doesn't regret coming to the academy with Natsume. Ruka also says that he will always support Natsume and Mikan's future when Natsume tells him of his fears of dying and leaving Mikan alone. Ruka promises to Natsume that he will take care of Mikan if something happens to Natsume in the near future. He is given mushroom earplugs by Hotaru, along with all of Mikan's friends, because of Reo visiting the school. He and Natsume are aware of Reo's plan to kill the ESP and are shocked of this. Ruka asks Natsume what they should do, but are interupted by Tsubasa and Tono who wish to help them out. Tsubasa and Tono explain to Ruka and Natsume that the only way the academy can remain peaceful is if the ESP disappears forever and they will have to prepare for a confrontation with both the ESP and Z. During their conversation, Koko reads Natsume's mind and says out loud about Natsume proposing to Mikan. Surprised and a bit hurt that Natsume hid this from him, Ruka asks about Mikan's reply, which she accepted, and he congratulates Natsume. Then Koko says about Mikan and Natsume's many kisses, which makes Ruka even more mad and he hits Natsume in a friendly manner while saying he will always support them. On the day of the concert, the boys split up to prepare their plot to overthrow the ESP. Ruka grabs Natsume and tells him that he must be careful and not leave his side. Ruka knows that Natsume is planning to risk his life if it means to save Mikan.
