Shirone Toujou (commonly referred to as Koneko Toujou) is one of the many female protagonists of High School DxD. She is a second-year high school student at Kuoh Academy and a member of the Occult Research Club, as well as Rias Gremory's first Rook.


Koneko uniform

Koneko is a petite girl with white hair and hazel eyes. Her body measurements are [B67-W57-H73 cm] [B26-W22-H29 in]. Her weight is [31 kg] [68 lbs]. The front of her hair has two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back has a short bob cut. She also wears a black cat-shaped hair clip on both sides of her hair, one of which contained the data on artificially making new Super Devils. She usually wears the Kuoh Academy girls' school uniform, without the shoulder cape. Koneko's height is 138 cm (4 feet 6 inches), making her one of the shortest female characters of the series.

In her Nekomata form, she grows a pair of white cat ears and a pair of matching white tails, and her eye pupils become more cat-like.

In her "Shirone Mode" that she used for the first time in Volume 16, Koneko can make herself grow older, and her attire consists of a short white kimono and a light blue skirt. Her bust size grows significantly larger also when in this mode, making her look more similar to her sister Kuroka.

In the anime, during the Rating Game between Rias and Riser Phenex, she wore black fighter's gloves with pink cat pawprints on the upper palm.


At the beginning of the series, Koneko had a quiet and cold personality, rarely showing any feelings or emotions, even when she was speaking. She was also the only one in the group who did not get along with Issei, often insulting and rebuking the latter for his perverted nature, although she reveals that she respects him for never giving up and considers him a hard worker. She shows the most concern for her comrades when they are in trouble, often lending her strength in fights. Koneko apparently has a problem with people calling her a midget (although the context of the phrase could be used to be called flat, as in bust size), as shown in her second battle against Freed Sellzen. This may stem from her insecurity about her own small body and bust size.

At the end of Volume 5, Koneko experiences a change in her personality after Issei helps her overcome her fear of using Senjutsu and now starts acting like a cat, often ends her sentences with "Nya" (にゃ), and/or showing emotions of love towards Issei. Her love for Issei grows so much that, at the beginning of Volume 11, she starts to go into mating season (though this was later stopped by her sister Kuroka). However, she still insults him when his perverted nature gets the better of him (at least when it isn't directed towards herself).


Born as Shirone, Koneko is a young Nekomata who is part of a rare species among her kind, called the Nekoshou. She was born between a human father and a Nekomata mother, her father was a scientist who did not acknowledge Koneko or was aware that she was his child, and merely used her for experiments. Her parents eventually died in a experiment accident. Her older sister Kuroka, however, omitted the truth and any other details about them from Koneko to protect her.

After losing her parents, she and her sister were later taken in by an unnamed Devil from the branch family of the House of Naberius, who reincarnated her sister as one of the members of his peerage. However, Kuroka's power as a Nekomata supposedly soon grew out of control, eventually causing her to kill her master and become a Stray Devil on the run from her pursuers. In actuality, he had planned to experiment on Koneko in his research about creating a Super Devil, causing Kuroka to kill him in order to protect her younger sister.

Following the incident and the failed manhunt that came after, Koneko was sentenced to death by the Devils in hopes of preventing another incident like Kuroka's from happening. However, Sirzechs Lucifer, one of the Four Great Satans, protected her and left her under his sister Rias' care. Due to the trauma she experienced with her sister's betrayal and murder of her master, she fell into a deep depression, eventually robbing her of nearly all of her emotions until Rias helped her out of it. It was around that time Rias gave Koneko her name and made Koneko her servant.

In Volume 3, Koneko followed Issei when the latter attempted to form an alliance with the Church Duo, Xenovia, and Irina Shidou, to help them reclaim the stolen Excaliburs in exchange for allowing Yuuto to break the Holy Sword. When asked by Yuuto and Rias who later found out about the alliance, she says that she doesn't want Yuuto to leave the team and become a Stray Devil. Later when Kokabiel attacks the Kuoh Academy, Koneko assisted in defeating the Cerberus Kokabiel took with him, before Kokabiel himself went to fight the Gremory Team and easily overwhelm them until Vali Lucifer came to retrieve Kokabiel under Azazel's orders.

In Volume 4, while enjoying time in the pool, it was revealed that Koneko and Asia cannot swim until Rias ordered Issei to teach them. Koneko was blushing the whole time, even revealing to Issei that she found him to be unexpectedly gentle, but still perverted, much to the latter's surprise. Koneko assisted in training Rias' other Bishop, Gasper Vladi, who was recently unsealed, chasing him around with garlic. During the peace talks between the Three Factions, Koneko was subjected to Gasper's time-stopping powers which were used by the Khaos Brigade in an attempt to kill the leaders of the Three Factions and was unable to help.

In Volume 5 when Rias returns to the Underworld for the Young Devils Gathering, Koneko was burdened by the thought of her being the weakest in the team but was afraid to use her Senjutsu at the same time due to the fear of being like her older sister, Kuroka, who killed her previous master. She overdoes her training in an attempt to overcome her weakness but instead collapses out of fatigue. During the party for the young Devils, Koneko meets Kuroka for the first time following the

incident that occurred years ago, with Kuroka intending to take Koneko back with her. While initially wanting to leave with her sister out of concern for Issei and Rias' safety, she eventually decided to stay after hearing Rias' speech that is full of love towards her (she tells Koneko that she is her Rook, and will not let anyone, including Kuroka, lay their hands on her). Kuroka, who could not help but be bothered with that much trouble, then attempted to murder the two of them, releasing a special mist that immobilized both Rias and Koneko. They are, however, saved by Issei who achieved his Balance Breaker on the spot and manages to beat Kuroka until Arthur Pendragon came to call both Kuroka and Bikou to retreat.

Before Rias' Rating Game with Sona begins, she spends some time with Issei, getting courage from him and asking him if he is afraid of her being a Nekomata. Issei replies that he isn't, much to her surprise, and says he would be there to stop her if she ever lost control, causing Koneko to develop feelings for him and becomes determined to use her Nekomata powers. During the Rating Game, Koneko faced off against Sona's Pawn, Ruruko Nimura, and defeated her after starting to use her Senjutsu. On their way home, Koneko starts to sit on Issei's lap while making a feline smile and exclaims, "Nyan♪”, much to the displeasure of the other girls.

In Volume 6 during Rias and Diodora's scheduled Rating Game, the match was interfered by the sudden appearance of the Khaos Brigade and the revelation of Diodora's alliance, the Gremory group facing Diodora's peerage along the way. She along with Issei and Gasper defeated Diodora's pawns who are promoted to Queen. She was last seen, with the other members, cheering Issei and Asia on their three-legged race.

Koneko's regular life force restoring sessions with Issei

In Volume 7, Koneko is seen doing a Senjutsu healing session with Issei in order to restore his life force that was lost while using Juggernaut Drive. She tearfully asks him to never use the Juggernaut Drive again (telling Issei she would hate it if he died) while telling Issei that there is a faster method to heal his lifespan (which would involve them having sex), but was interrupted by Rias and Asia. She is later seen assisting her group in their battle against Loki and Fenrir.

In Volume 9, Koneko, along with Akeno, Rias, and Asia, wants to spend time with Issei before he leaves on his trip to Kyoto. She offers to do several days of Senjutsu treatment for him that night while wearing a lonely expression (while Issei notes that she hasn't been this daring with him before), openly competing with the other girls for his affection. After Issei, Xenovia, Asia, and Kiba come back from their trip, she openly shows her displeasure at Issei for not contacting her when they were in trouble with the Hero Faction. After Azazel announces that Ravel Phenex will be transferring to Kuoh Academy, she openly shows her displeasure to the news, alluding to the natural cat and bird rivalry.

In Volume 10, Koneko, along with Asia and Akeno, help Issei to get rid of 'curse' on his heart by Raynare and his fear that the girls around him don't actually like him, confessing that she does in fact like him.

In Volume 11, Koneko went into mating season because of her feelings for Issei but was deemed too young to risk pregnancy. Fortunately, her sister Kuroka was able to seemingly negate her mating season, allowing her the time to reach physical maturity. Her relationship with her sister also improves, after seeing her sister protect her from an incoming attack and agreeing to Kuroka's proposal of teaching her a Nekomata's Senjutsu and Youjutsu. After Issei asks her to recognize Kuroka as her sister, Koneko asks him to make her his bride after confessing that she loves him.

Koneko in the bath with Issei

During their break from training and the girls talks about Issei, Koneko recalled of how she and Gasper was saved by Issei and protected them from the Grim Reapers. After returning from their training, Koneko appeared in Issei’s room after Kuroka barged in and apologized to Issei for unable to stop her from ruining his moment with Rossweisse. Koneko panicked after Kuroka tells her if she wants to reserve Issei’s child and she somewhat agrees and strips her garments and went on top of Issei with him noticing how bolder Koneko became and the four decided to sleep together.

Koneko and her team travels to Valhalla to cheer for Issei and his team in their match. Koneko and her team celebrated at the Hyoudou Residence for passing the preliminaries along with rival teams.
