HistoryEdit

Tobio is a descendant of the Himejima clan. When Tobio was born with the Sacred Gear Canis Lykaon, it was one of the rare instances where it already had its Balance Breaker fully activated and because of this in his childhood his grandmother, Ageha Ikuse, sealed his Longinus, Canis Lykaon, for his safety and had his memories erased. Tobio had since lived a normal life with his grandmother and childhood friend, Sae Toujou. At some point he joined and became a member of the Grigori and met Walburga. At some point, the previous "Ouryuu" had been causing trouble for him and Vali.

In Volume 25, Tobio had a secret meeting with Ajuka on a rooftop garden in the human world, it is revealed that Tobio had been moving behind the scenes for Ajuka to locate and spy on Mitsuya Kanzaki, a young man who controls two Longinus. Tobio and Ajuka were both conflicted if they should bring him over to their side since all the Longinus wielders will be needed when they come in contact with ExE, but was worried for what kind of phenomenon might happen should he come into contact with the current Two Heavenly Dragons, especially Issei with Telos Karma.

Tobio appeared after Mitsuya Kanzaki saved Gorou Hyoudou from the Grim Reapers. Tobio views him as a nemesis of Ajuka and the one who controls Innovate Clear and Telos Karma and because of this the Grigori came to view Mitsuya as a dangerous man. As things started to heat up between Tobio and Mitsuya, Gorou stepped in to stop the fight and Tobio apologize to him for his behavior.

Tobio and his Slashdog team celebrates at the Hyoudou Residence along with their rival teams. Tobio tells Issei if he gets a match, he would want to fight against Issei and Vali much to Issei’s surprise.

In True Volume 3, Tobio and his team arrived to the Shinkansen platform to be escorts for Issei and the group to Kyoto and he has personal things to take care off. Tobio took part of the meeting with Suzaku Himejima and Sun Wukong in the reception hall of the giant mansion about the Five Principle Clans offering their full support to Kyoto and he tells them that Enma hasn’t joined Hades and the Rulers of Hell, leading them to believe that Hades has a plan. Tobio explains that Kyoto was chosen to make Enma mad because the Three Great Powers was made in Japan and were to make them mad as well, because the team, the Five Principal Clans, Sun Wukong, his team and the Hero Faction team will act as security. He started to explain that the Rulers of Hell have troublesome underlings and Kyoto is a important town for Japan because of the history, culture, economy and spirituality and later watched the Hero Faction apologized to Yasaka for the trouble they caused last year and she accepted their apology, but some Youkais haven’t forgiven them so she decided to entrusted them to protect the place, with Cao Cao agreeing to protect the place with body and mind, leading Tobio to smile.

Tobio and his Slash/Dog team engaged the artificial Devils at the west side of the pseudo-barrier space that resembled Urakyoto with Tobio facing Gressil while his team dealt with the remaining artificial Devils. Tobio told Gressil that he was lucky that he didn't face Cao Cao because he would have been quickly turned to dust as Tobio activated his Balance Breaker, stating that Gressil was also lucky that Issei couldn't go all out during their encounter, which allowed him to survive. Tobio asked what Gressil's goal was after he surpassed Balberith and Verrine as Tobio became disgusted by Gressil's reasons for rampaging, stating that due to the possibility of Gressil’s evil intentions reaching those precious to Tobio, he would cut Gressil before that could happen as he activated his Abyss Balance Breaker and engaged Gressil in battle. During their battle, Tobio noted that Gressil's physical ability increases each time he fights as Tobio used his darkness to disperse Gressil's attacks, taunting him that only a real Satan-class or God-class could surpass his darkness and damage Tobio. Tobio defeated Gressil after the latter let his guard down due to developing a resistance against Tobio's blades as Tobio revealed that his blade has different aura wavelengths which allowed it to bypass Gressil's Resistance as his body only remembered one of his aura wavelengths. Tobio then finished off Gressil with his scythes, stating while Gressil is similar in power to Balberith and Verrine, it takes more then raw power or demonic power to become a true Super Devil. After finishing his fight Gressil, Natsume Minagawa approached Tobio, asking if he defeated Gressil, to which Tobio stated that it ended as she stated that the rest of the Slash Dog team defeated the artificial Devils.

In True Volume 4, Tobio and his team decided to do the surveillance around London after the other members of Team DxD make preparations for their departure to England to fight against Hades and Angra Mainyu, and instructed Lavinia to travel with the other team.

After the battle, Tobio and the other members celebrated their victory at the garden of the Hyoudou Residence.

EquipmentEdit

Jin

Tobio's Sacred Gear, Canis Lykaon

Canis Lykaon (黒刃の狗神ケイネス・リュカオン, Keinesu Ryukaon): Tobio possesses the Longinus Canis Lykaon, which takes the form of a large black dog whom he named Jin that acts as an independent avatar type with its own instinct. It has the ability to produce blades and shadows from its body, can transform itself into a sword, and can also move through and extend blades from any shadows, which can be spread as far as the user's sight. Tobio has mastered his Longinus to a tremendous level, to the point of being able to slice apart concepts and the very fabric of space-time. In addition, he can also make attacks on his body melt into shadows as protection as well as submerge within shadows to reappear out of others.

  • Scythe (鎌, Kama): Tobio can produce one or more scythes which he uses as his main weapons for melee combat. Tobio's immense mastery of his Sacred Gear allows his scythes to damage even the souls of his opponents. Due to possessing the power of the "Ame no Ohabari"; which was used to kill the God of Fire; Hi-no-Kagutsuchi, his scythe can also produce cursed flames colored black and crimson.
Night Celestial Slash Dogs

Balance Breaker: Night Celestial Slash Dogs

  • Night Celestial Slash Dogs (夜天光の乱刃狗神ナイト・セレスティアル・スラッシュ・ドッグズ, Naito Seresutiaru Surasshu Dogguzu): Canis Lykaon's original Balance Breaker, which Tobio had already unlocked from the moment he was born. Tobio is covered in darkness and transforms into a humanoid black hound with six tails, while Jin transforms into a large, fully-grown black hound. In this form, not only does Tobio gain enhanced strength and speed, but he can also extend his shadows beyond the range of a huge building complex and create an innumerable amount of blades in them, capable of tinging the sky and earth in darkness.
  • Perfectus Tenebrae Lykaon et Fortis Densus Laelaps (深淵なりし冥漠の獣魔、英傑であれ常夜刃の狗神ペルフェクトゥス・テネブラエ・リュカオン・エト・フォルティス・デンス・ライラプス, Perufekutusu Tenebrae Ryukaon Eto Fortis Dens Rairapusu): Tobio's Abyss Side Balance Breaker, which he achieved after becoming accustomed to using his Sacred Gear and polishing Night Celestial Slash Dogs to the limit. By reciting a curse-like chant, his entire body becomes covered by darkness and takes the form of a humanoid black beast. This form has forelegs, hind legs, a tail, and massive jaws that resemble a dog's. In this form, Tobio keeps his ability to sprout immense blades from his extended shadows, while the darkness in the surrounding area also forms enormous dogs with jet-black fur that attack opponents with blades carried in their mouths. These dogs can also move through shadows much like Tobio and Jin to attack the blind spots of their foes.

TriviaEdit

  • Tobio's birthday is on the 4th of May[1].
  • His first name Tobio (鳶雄) means "Male Black Kite".
    • His surname Ikuse (幾瀬) means "Several Rapids".
  • Tobio is the second Japanese human to possess a Longinus Sacred Gear.
  • Canis Lykaon means "Dog Wolf". Lykaon is a transliteration of the Latin spelling "Lycaon" which is derived from the word "Lykos" which means "Wolf". The wolf part could possibly be a reference to Lycaon the king of wolves in Roman mythology and this would refer to Tobio's ability to control Jin and his multiple jet-black dogs.
  • Perfectus Tenebrae Lykaon et Fortis Densus Laelaps means "Perfect Darkness Wolf and Strong Dense Hunter".
    • Why Laelaps means "Hunter" in this case is because Laelaps is the name of a dog in Greek mythology that always caught what he hunted and so would refer to how Tobio's dogs always catch their 'prey'.
  • Tobio works a part-time night shift as the bartender at the Black Dog BAR, a bar created by Azazel. In addition to this, he sometimes cooks at a restaurant in the same building on the first floor below the bar, which is on the second floor.
    • The bar seems to have been named after Tobio himself (sharing said name with Jin).
  • Tobio is listed among the strongest humans, along with Cao Cao, Arthur, Vasco, and Mitsuya.
  • Tobio is the first protagonist from another Ishibumi work to appear in High School DxD, starring in SLASHDØG. The second one is Mitsuya Kanzaki, the protagonist of Ishibumi's first work, Denpachi.
