Hiroomi Nase (名瀬 博臣 Nase Hiro'omi) is one of the main characters of the Kyoukai no Kanata series. He is a third year high school student in the anime and Mitsuki's older brother, as well as an avid siscon. Like Mitsuki, he comes from the prestigious Nase family. Due to his Spirit World Warrior abilities he is extremely sensitive to cold, causing him to often wear a scarf or muffler.[1]


Hiroomi Nase

Hiroomi has green eyes and black bowl cut hair. Due to the nature of his Spirit World Warrior abilities, he is often dressed in the school's winter uniform — a white dress shirt, a dark blue blazer, and a green necktie, and a thick scarf to keep himself warm. His back is severely scarred from a past incident restraining Akihito's youmu rampage.

Through the series Hiroomi is seen sometimes wearing different scarf or muffler with other coloring and patherns. An example in episode 5 he wore a blue scarf with white stripes and in episode 7 a black scarf with green stripes. He is mostly seen wearing a black one with red stripes.

During his performance in episode 6, he wears different clothing, instead of his school uniform he wears a white sleeveless t-shirt, a short black sleeveless vest whith green, white and yellow buttons on, white wrist bands, a black and white trouser with a small chain, black shoes and finally a plain black scarf to finish off.

In Kyoukai no Kanata : Mirai-hen during work he adores a black suit underneath a green shirt, black vest and a red necktie. A long light grey coat adores on his sholders. He seems to be wearing black gloves as well. He wears a scarf.

Hiroomi in the movie


Hiroomi is initially introduced as a hopelessly laid-back person with a sister complex and an inclination towards teasing Akihito.

But as the plot progresses his serious side is shown, and he proves to be a highly skilled spirit warrior with formidable intellect and judgment. He is also critical of his sister, Mitsuki, for the first time when fighting off dreamshades in the presence of the "strong dreamshade with no physical form".

However, in general he maintains his goofy, laid back attitude. Like his sister, he also has a habit of teasing Akihito and affectionately calls him "Akkey." Another way of teasing Akihito is putting his hands in Akihito's armpits. He also eventually agrees that glasses do look nice as a result of their relationship. He also has a thing for little sisters, not only for Mitsuki, evidenced when he is stimulated by Ai upon her "cute imouto" gestures. He is also shown as a pervert who doesn't mind being naked in front of girls. Hiroomi is also not ashamed but rather proud of his "sister complex" fetish and often compares fetishness with Akihito.

Despite all this, Hiroomi poses as a supporting brother and faithful friend to his two sisters, Akihito and Mirai, and everyone (with the possible exception of Mitsuki) accepts him as he is.

History Edit

Two years before the start of the series, Hiroomi tried to subjugate Akihito at Izumi's request. During that mission, Miroku Fujima injured Akihito to the point that Akihito's youmu side surfaced. In that form, Akihito almost killed Hiroomi.

In the Mirai-Hen movies he is shown to have succeeded the Nase household in the wake of Izumi's disappearance. Hiroomi appearance in the film changes as he nows wear a black trenchcoat but still with his signature scarf. It is shown that his skills has improved drastically in creating a barrier cage.


Mitsuki Nase

Hiroomi's younger sister. They often bicker but quickly reconcile. He's shown to have a strong sister-complex involving her, blushing or suffering a nosebleed when she calls him "Onii-chan." His ringtone is Mitsuki saying "Onii-chan, I love you". He loves his younger sister a lot and always tries to protect her from harm. Even so, he sometimes hides secrets from her because he doesn't want her to worry.

Akihito Kanbara

After Hiroomi's assignment to kill Akihito two years ago, Hiroomi and Akihito have been hanging out, often joking with each other. A running gag is Hiroomi's tendency to put his hands under Akihito's armpits, much to Akihito's annoyance and once leading Mirai to comically question whether they were secretly 'seeing' each other. Hiroomi cares about Akihito and sees him as a good friend, shown when Izumi asked him to kill Akihito to which he replied, "Like I could kill him".
In the Mirai Hen film ending, he and Mitsuki are shown overjoyed upon the return of Mirai and Akkey. He jumps on Akkey and it is implied off screen that he cried upon his return.

Izumi Nase

It is shown that they do not share a close bond, but rather one of respect, as he states that he looked up to her as an idol. But at the end of the anime series he renounces her, saying that he wants to be nothing like her. In the film's flashback, Izumi reluctantly allowed herself to be injected with a parasite type youmu enable for her to become stronger and protect those she loved.
In the film Mirai Hen after Izumi's disappearance, Hiroomi took over the Nase household but had to face off with Izumi at it is revealed that she was the hooded figure attacking various spirit warrior under the control of a parasite youmu. He and Ayaka tracked Izumi down but Ayaka noted and teleported that Hiroomi could not do to his love for Izumi hurt his sister. In the final face off with Izumi, Hiroomi states that he should not have been chasing after her but rather supported and walked together with his big sister instead. The film ends with the Nase siblings reconciling.


A key trait common to the Nase family, Hiroomi possesses the ability to erect barriers called Glaciate Barriers, which act as a defensive barrier and an obstacle to most youmu. He shows commendable skill in erecting these barriers, which held its ground during the appearance of the Hollow Shadow, although it was unable to withstand Akihito when he transformed into a youmu.

Hiroomi can make youmu disintegrate using his scarf. The scarf only needs to touch a youmu to disintegrate them, and Hiroomi has used his scarf to slice down youmu upon contact or outright destroy them by trapping them inside the scarf itself. Apparently, this ability is responsible for his sensitivity to cold. While fighting, sometimes he can't focus if Mitsuki is worrying about him.
