Mirai Kuriyama (栗山 未来, Kuriyama Mirai) is the heroine of the Kyoukai no Kanata series. She is a first year student and a member of the school's Literary Club. She comes from a bloodline of Spirit World Warriors with blood-manipulation abilities. However, because this kind of ability is considered as heretical among Spirit World Warriors, she became an existence that is shunned by many.
Mirai is a petite girl with light brown eyes and strawberry blonde/pink hair, which is styled in a bob-cut with bangs that reach her eyebrows. At school, she wears a loose pink cardigan over the school uniform and black tights or similar hosiery. However, Mirai began to attire a vest-like sweater over her school uniform, identical to the color of her cardigan.
Mirai wore the cardigan to conceal a bandaged wound (a gash on the right forearm in the light novels; a round wound on the right palm in the anime) which she always prepares whenever she needs to use her ability. In the light novels, she also wears a set of bracelets to secure the bandages to her wounds. She then uses a golden ring to activate her ability.
Her most distinguishable accessory is the pair of red thick-rimmed glasses that she proceeds to adorn at all times, which she soon changes to gray for a while before she soon changes to red again.
Clumsy and a bit shy, Mirai rarely stands out in school. In fact, she struggles pretty much in life; she has to earn her own money to make ends meet, but her constant fear of actually encountering a Youmu used to prevent her from earning an income from slaying Youmu, which most Spirit World Warriors take on as part of their profession. To make things worse, her hobby of writing blog articles about bonsai is often ridiculed in the Internet. In contrast, Mirai is a focused Spirit World Warrior, although her clumsiness still shows on occasion. Her movements in battle demonstrate a certain degree of knowledge in how to fight, although she lacks the experience in actual combat due to her issues with Youmu encounters. After bonding with those around her, Mirai began to feel more confident about defeating Youmu and became quite the experienced Spirit World Warrior. She is fond of saying the words "How unpleasant!" (不愉快です！, "Fuyukai desu!") when agitated.
Mirai is the sole survivor of a Spirit World Warrior clan with the ability to control blood. Without any relatives left, she was adopted by the Inami family for some time and became friends with the family's youngest member, Yui. (In the anime series, Yui's sister Sakura becomes a second friend.) But when the Hollow Shadow possessed her best friend Yui Inami in an encounter, Mirai killed her in an attempt to save herself. Afterwards, Mirai was hated by the Inami family, especially by Yui's little sister, Sakura Inami.
After being thrown out from her adopted family, Mirai was taken in by Izumi Nase, thinking that her powers would be enough to kill Akihito Kanbara, a half-Youmu that was determined as a threat to Nagatsuki City.
Story (Anime Series)EditMirai meets Akihito for the first time when she was standing at the rooftop of the school Akihito is studying in. Their first meeting was far from pleasant for Akihito when he ended up being stabbed by a sword she conjured using her blood. Akihito survived due to his youmu lineage, but it did not stop Mirai from attacking him throughout the week that followed. Mirai later reveals that she is currently struggling as a Spirit World Warrior due to her lack of experience in slaying youmu for a stable income. With some support from Akihito, who agreed to help, Mirai manages to kill a youmu for the first time.
News soon spread about the Hollow Shadow approaching Nagatsuki City and Mirai quickly heads to the location of the powerful youmu to face it herself. Here, she meets with an old friend named Sakura Inami, who is now hostile against her because of the death of her sister Yui that she blames on Mirai. Both Sakura and Mirai are swallowed by the illusion created by the Hollow Shadow's presence, and Mirai narrowly escapes Sakura with the help of Akihito, who pursued her after learning of her bold decision to take on the youmu singlehandedly.
Akihito and Mirai soon find themselves still stuck inside the illusions of the Hollow Shadow, but they found a way out when the youmu itself manifests in front of the two in the form of Yui Inami. Despite the memories of losing Yui haunting Mirai, she manages to defeat the youmu enough to dispel the illusions it created. However, it attempts to take over Akihito's body in a desperate attempt, leaving Mirai with no choice but to stab Akihito in spite of the dangers to his life. Akihito survives the attack and Mirai officially becomes friends with Akihito ever since, eventually joining the Literary Club later on. However, due to her rash actions during the Hollow Shadow incident, her Spirit World Warrior license was confiscated, leaving her out of action and without a source of income within the month that followed.
With the help of Akihito, Mirai slowly becomes acquaintances with Hiroomi and Mitsuki Nase, as well as Ai and Ayaka Shindou, who agreed to give Mirai a part-time job as a photography model for the meantime. Her peaceful life, however, was once again shattered when Sakura Inami returns as a transfer student. The two later engage in battle once more, although Mirai defeats Sakura this time. Afterwards, the weapon Sakura has been using to gain powers similar to that of a Spirit World Warrior turns against her, causing Mirai to protect Sakura from the onslaught. Mirai decides to reconcile with Sakura after what happened, which the latter reluctantly agrees to. Sakura later becomes Mirai's roommate.
- Mirai was born with the ability to manipulate her blood in various ways such as shaping and solidifying it to form constructs (She is limited to this ability as to how much blood she has). She can also use it to burn through things, as shown in a few episodes.
Mirai first met Akihito on the roof of the school building while trying to commit suicide. Afterwards she tried to kill him only to find out that he was basically immortal. She went on trying to stab him for practice until eventually they became friends. Akihito was the one who got Mirai over her fear of Youmu and even though she's always complaining about how unpleasant he is, she still cares about him. In Episode 12, when Mirai was disappearing, she thanked Akihito for allowing her to know him, and she expressed how grateful she was for the opportunity to fall in love with him, admitting her feelings.
After finding out what Mirai has done to her older sister, she began to hunt her down, planning to kill her and get revenge for Yui. After a battle with Mirai, Sakura came to realize that she is not a Spirit World Warrior and becomes friends with Mirai, eventually developing a bond with her. She currently lives in Mirai's apartment. She seems to care about Mirai to the point of frantically asking where she was and kicking Akihito hard when he didn't answer.
Mirai meets Mitsuki after Akihito introduces them to each other. Although Mitsuki was cautious of Mirai at first, she still develops a bond with her after getting to know her better and often has girl talks with her from time to time.
