Beyond the Boundary Kyoukai No Kanata

Just as there is a light at night and darkness in the day, there will always be darkness in the world. At the same time, the world will never be engulfed by the darkness. In that mix of ambiguous colors, everything moves on: our fates determined”

— Akihito Karbara

For a starter, we have Mirai Kuriyama, a spirit world warrior with the ability to control her blood. Akihito Kanbara, another spirit world warrior,  is an immortal youmus because of  his fast healing abilities, which he got by being a half Youmu. Youmus are mysterious creatures that roam our world. They come in all shapes and sizes, and some are human, just like Akihito. Some are harmful and go after humans. It is unknown why they exist. A few of the warriors from the spirit world that make money by killing Youmus. These creatures vary in their appearance. They have forms similar to that of animals or non-living objects.

The similarity among all youmu is their tendency to manifest an ore-like stone that contains the powers of that youmu when slain. These stones are sought after due to the value Appraise gives to them. Humans normally do not possess the ability to see youmu, which can only be seen by spirit world warriors and other youmu.


One day, Akihito finds Mirai on the rooftop of his school, ready to throw herself off a building. So, like any sensible being, he tries to save her. However, the outcome was not as abiding for he then took her sword to the chest. A sword which is made from her blood. It turns out she is a spirit world warrior, and the last survivor of the Kuriyama clan. She tries to kill Akihito over and over, and succeeds in that a few times. At the end, it turns out she was using him as a way to practice killing Youmus.

Mirai is from the cursed Kuriyama clan, with the ability to manipulate blood, which causes her to get anemia due to the blood loss. The clan has the ability to control their blood and craft weapons, such as the one Mirai is shown to possess. Despite the ability being unimaginably interesting, it also made the Kuriyama clan cursed in the spirit world. For this fact, Mirai felt alone and isolated, which is why she tries to kill herself in the first episode despite her power.

Akihito, a sophomore in high school, makes it easy for a young audience to identify with him. Despite being immortal, he still feels pain when he gets injured. Which is the main reason that he tries to avoid being stabbed by Mirai at the beginning of the anime. However, Akihito finds Mirai attractive and thus calls her a spectacle beauty; regardless of the fact that she is trying to kill him.

Akihito likes girls with glasses, and hints the nickname aforementioned because she is cute in glasses.

The spirit world warriors society is like a government for the spirit world. It watches over important events, registers spirit world warriors, makes and keeps laws, and maintains records of youmu. Appraisers are persons officially recognized by the Spirit World Warrior Society to accept youmu stones and designate monetary values to them based on the type of youmu.
