Tsubasa Jūmonji (十文字 翼 Jūmonji Tsubasa?) is a major character of Kyōkai no Rinne, serving as a rival to Rinne for Sakura’s affection and for their differing philosophies on how to deal with spirits. Like Sakura, he can also see spirits, but unlike Rinne, he often brutally attacks them with "sacred ashes" instead of trying to put them to rest, which can serve to turn them into evil spirits. He comes from a wealthy family of exorcists, and it is hinted that he is Christian.
He has short black hair and dark gray eyes, and is usually wearing earrings, a cross, and a long dark coat over a lighter shirt. He has worn other outfits as well, like his yukata, a tuxedo, and swim trunks, and he doesn't dress in the school's uniform.
Tsubasa was much of a lone wolf due to his ability to see ghosts, until he met Sakura Mamiya. Now as a teenager, he is much more confident in himself and openly expresses his attraction in Sakura. He's a bit of air-head himself and is very quick to assume. He easily falls for stupid tricks like Ageha does, such as buying a "romance pendant" for 5000 yen, but he has some common sense. He is cruel to ghosts, giving them rough treatment and never listening to what they have to say, but has slowly come to understand Rinne's methods and has changed his exorcism tactics to less brutal attack though he remains using his sacred ashes. He tends to jumps to conclusions, especially when something concerns Rinne and Sakura's relationship.
HistoryTsubasa spent much of his life traveling around chasing ghosts with his family. He had transferred into Sakura's Elementary school, expecting nothing but his normal misery, until he discovered that Sakura could also see ghosts. Since he had never met anyone else who understood him, and after promising that they would keep their powers secret, Tsubasa fell for Sakura. Due to his family’s business, he had to leave again. He buried his power stone in the schoolyard tree which is a power spot called “haunted cedar”, to increase its spiritual power, and he kept a picture of Sakura.
5 years ago, at another Elementary school, he drove a famous spirit nicknamed “Hanako the Toilet Girl” out of the bathroom, by trying to exorcise her.
At one middle school he was enrolled for a short time, a girl named Ayame Sakaki took interest in him as they are on the same business, but was never able to get to know him.
When Tsubasa returned to Tokyo, he was transferred into Sankai High into Sakura and Rinne's class. As he was dealing with an innocent spirit called Usui, he witnesses Rinne and Rokumon flying, and believing the duo to be ghosts, throws his sacred ashes at them, which causes damage to Rinne while wearing his Haori. As he is introduced to the class, he immediately comes to Sakura and tries to remind her who he is, constantly repeating "it's me". When Sakura finally recognizes him, by reading his written name on the blackboard, Tsubasa is relieved, remembering how he first met her, then asks Sakura to go out with him to which Miho and Rika question whether or not Sakura was already dating Rinne. Rinne happens to enter the room, and Tsubasa learns that Rinne is Sakura's classmate and displays disbelief. Rinne then declares that his methods are wrong, but Tsubasa believes that Rinne is talking about his declaration of love to which he demands to know if Rinne and Sakura were indeed going out, and so begun their rivalry. They argued on how to deal with Usui, but he accepted to see Rinne’s way of helping him rest in peace. He then fights Hanako, who continuously borrows power from an evil entity called Toichi, to get her revenge. However, he gets surprised as he sees Rinne deal with Toichi with his Shinigami skills, and he apologizes to Hanako for the fact that she could have become an evil spirit because of himself, and lets Rinne take her to the Wheel of Reincarnation.
And so, he joins Rinne and Sakura on their ghost exploits, and tries countless times for Sakura to return his affection and gets jealous whenever she and Rinne are together. He has become more lenient towards some spirits, having realized that not all are evil, though he remains using his sacred ashes. He even gets to enter in Kyoukai many times, mainly because of the troubles caused by Rinne’s father, Sabato.
He invited Sakura to go back to her elementary school to dig up his power stone, and learned a nameless evil spirit possessed the spirit of a former classmate Yota and used the power stone to become powerful. Rinne separated the evil spirit from Yota and enabled Tsubasa to retrieve his power stone before purifying the evil spirit, and Sakura allowed Yota to move on.
As his power stone became corrupted, and as he became mad the week after of Rinne meddling between him and Sakura, Masato appeared to him and gave him the book of devils, which can be used in conjunction with the tainted power stone to curse Rinne, not only to satisfy his grudge but at the same time seize Tsubasa’s soul and take it to hell. After cursing Rinne many times unwillingly, Tsubasa’s power stone gets pitch black, almost devoid of light, but by getting cursed himself, the power stone was purified and Tsubasa then uses it to attack Masato who retreats.
A wicked yōkai called the Nine-Tailed Fox that escaped from the Mortal Census Bureau, came to possess him while he was sick, to fulfil his promise to curse Tamako's grandson Rinne. And Tsubasa used it as an excuse to settle his own grudge against Rinne for thwarting his chance to be alone with Sakura, but he and the fox end up defeated, and he would still pretend he was being controlled by the fox, although Sakura did realize he was using him.
He meets Ayame again, when her vengeful spirit chases a Komainu spirit from her Shinto Shrine that went on loose. Upon learning that her spirit, which is a projection of her true feelings, that emerged ever since Tsubasa left her school, would return to her body if Tsubasa goes on a date with her, he accepts and takes her to the amusement park, much to her delight.
He would meet Ayame again occasionally during her business or when her spirit would go on the loose as he and Ayame don't meet very often, and despite trying to satisfy her feelings, it seems apparent he tries to avoid being alone with her, by having Rinne and Sakura along, since he remains fixed on Sakura, much to her disappointment.
Sacred Ashes: Tsubasa throws small balls of sacred ashes at spirits. They are meant to be effective on evil spirits and seem to have a paralyzing effect. However, they have on several occasions, been brushed off for their lack of effectiveness. He also uses the ash balls as gun ammo, such as a bazooka.
Bible: Tsubasa smashes the head of his opponent with the corner of his book. It has been called "a devastating blow." He uses this attack sparingly, saying it requires about a week to use it again due to how much energy it requires.
Power Stone: A power stone shaped like an amulet. When purified, it can summon large drop-shaped sprites of light to pummel enemies into submission.
Sword and Holy Water: A holy sword that when splashed with holy water is capable of destroying barriers or crossing boundaries. It has yet to be shown succeeding as Tsubasa is usually pitted against barriers created by Annette's much more experienced grandmother. It remains a mystery where Tsubasa carries the sword.
He has the ability to see spirits, and also the power of exorcism, although he was rough on spirits at first. After seeing Rinne's ways of handling spirits though, he starts to soften up.
After learning that Sakura could also see ghosts, Tsubasa developed feelings for her and continued to harbor those emotions until they were reunited in Sankai High. Tsubasa confuses her concern for him as a sign of love and has fallen for a Damashigami trick, as he was told that there was a way to win her heart. Tsubasa is persistent but can't totally take a hint.
Tsubasa considers Rinne a rival for Sakura's love, despite the fact that his romantic relationship with her is only one-sided. Unlike Rinne, Tsubasa has very little tolerance for helping ghosts pass on to the afterlife peacefully and instead prefers to forcibly send them away whether they have any lingering business in the land of the living or not. These differing philosophies immediately bring Rinne and Tsubasa into conflict with one another. However, the two can reconcile their differences when it's necessary and Tsubasa has acknowledged Rinne's more peaceful tactics towards spirits as well.
Tsubasa knew her when he was elementary school. She took interest in him as they were in the same business, but was never able to talk to him. When they reunite, it proved difficult for her to admit she wished to go out with him, but Tsubasa accepted much to her delight. The two remained on good terms, but Tsubasa still sets his eyes on Sakura, much to Ayame's annoyance who hopes to go on another date with him without the company of anyone else.
As a Damashigami who robbed his soul when they first met, he doesn't trust her, but they can sometimes be on agreements.
After being used for in his second attempt to harm Rinne, Tsubasa felt disgraced being manipulated by a demon and since then resents Masato.
