Beyond the Boundary (Japanese: 境界の彼方, Hepburn: Kyōkai no Kanata) is a Japanese light novel series written by Nagomu Torii, with illustrations by Tomoyo Kamoi. The work won an honorable mention in the Kyoto Animation Award competition in 2011. Kyoto Animation has published three volumes since June 2012. An anime television series adaptation, produced by Kyoto Animation, aired in Japan between October and December 2013. An original video animation episode was released in July 2014. A two-part anime film project premiered in March and April 2015.


One day, high school student Akihito Kanbara instinctively goes to save his fellow schoolmate, Mirai Kuriyama, from committing suicide. Following his pleas, Mirai suddenly stabs Akihito with a sword formed out of her own blood and is shocked to discover that Akihito is an immortal "half-youmu"—the offspring of a supernatural creature, called a youmu, and a human. After learning that Mirai is a Spirit World Warrior (異界士, Ikaishi)—specialists who protect humans from being affected by youmu—and the last surviving member of her spirit hunting clan, their lives become intertwined as Akihito seeks to help Mirai gain the confidence to kill youmu so that she may stop attempting to kill him as practice.

In Beyond the Boundary, youmu (妖夢, yōmu, alt. Dreamshade) are supernatural creatures that appear throughout the series and can only be seen by those with a supernatural affinity. They are said to be the physical materialization of human animosity such as negative emotions including hatred, jealousy and malice and therefore as long as humans exist, youmu will continue to exist. They can exist in many types of shapes and forms with some even having a human appearance. There are also rare cases when a youmu and a human mate may produce an offspring, which is called Half-Youmu (半妖, Han-Yō, "Half-Shade"). Most youmu are relatively docile and coexist with humans even without them being aware of their presence. However, there are times when a youmu's behavior upsets the balance, so the Spirit World Warriors are sent in to kill them. Upon death, a youmu produces a Youmu Stone (妖夢石, Yōmu Ishi, alt. Dreamshade Stone) which can be appraised and traded, hence providing a source of income for a Spirit World Warrior.



Akihito Kanbara (神原 秋人, Kanbara Akihito)
Voiced by: Kenn, Mei Tanaka (young)[3] (Japanese); Clint Bickham[4][5] (English)
Akihito is a second-year high school student with short blonde hair who is an immortal half-youmu, the offspring of a youmu and a human. He has the ability to heal quickly from any wound albeit still experiencing pain. Due to this Mirai uses him as practice to help overcome her fear of killing youmus. He is a member of the Literary Club. He has an attraction to girls with glasses, as shown by his spontaneous compliments to Mirai as well as being disdainfully teased for it by Mitsuki. If Akihito's physical human body finds itself in a severe weakened state, his dormant youmu half emerges, physically changing his body into a hideous feral appearance which then proceeds to go on a rampage. Akihito's youmu half is extremely powerful, able to easily overwhelm supernatural cages and barriers that attempt to contain it in addition to having enough destructive force to physically devastate whatever landscape surrounds it. Akihito implies that because of his youmu half, the Nase clan are not exactly his friends but instead people who are tasked with watching him should his youmu-half ever go berserk and killing him if necessary. Following a youmu transformation, Akihito falls into a state of depression due to almost killing Hiroomi in a past rampage. Akihito's youmu half holds the greatest destructive power of all youmu and is referred to as "Beyond the Boundary".
Mirai Kuriyama (栗山 未来, Kuriyama Mirai)
Voiced by: Risa Taneda[3] (Japanese); Krystal LaPorte (series),[4][6] Kira Vincent-Davis (films) (English)
Mirai is a first-year high school student with short, light pink hair styled into a bob, and wears red-rimmed glasses, leading Akihito to call her a 'bespectacled beauty', much to her dismay. She has the ability to manipulate blood, which is unique even within the scope of the Spirit World. Overuse of her ability results in severe anemia while at the same time it causes her to feel isolated and seemingly attempts suicide by jumping off the roof of the high school until she is saved by Akihito. She is summoned to kill Akihito but ends up harboring feelings for him. She is often ridiculed due to her constantly posting about the misfortunes in her life on her blog and Twitter account. She usually uses the phrase, "How unpleasant" (「不愉快です」, "Fuyukai desu") to describe most situations, particularly at remarks made by Akihito. Despite her cursed blood lineage, she was adopted by the Inami clan and befriended their youngest daughter, Yui Inami whom she killed out of fear after Yui was possessed by the Hollow Shadow—an act of which Mirai is deeply regretful and hence gave root to her fear of killing. Her signature weapon is a carmine colored sword formed out of her blood.
Mitsuki Nase (名瀬 美月, Nase Mitsuki)
Voiced by: Minori Chihara[3] (Japanese); Monica Rial[4][7] (English)
Mitsuki is a second-year high school student with silky, dark hair. She is the younger sister of Hiroomi and Izumi and the President of the Literary Club. She enjoys teasing Akihito, such as claiming to be his childhood friend (in actuality, Akihito first met her in junior high; the OVA revealing it was the same incident in which his youmu half nearly killed Hiroomi). Although she calls her brother Hiromi a "pervert" and calls him "aniki" (respected older brother) to sound less informal, she really adores him and holds him very dear to herself. Her clan governs Spirit World Warriors in their area. Izumi instilled in her the belief that Spirit World Warriors are to be alone all their life, due to their duties and therefore resulted in Mitsuki missing out on experiences with her peers while growing up. She has a rodent-like youmu called "Yakiimo" as a familiar. Like her brother, Mitsuki is capable of setting up cages.
Hiroomi Nase (名瀬 博臣, Nase Hiroomi)
Voiced by: Tatsuhisa Suzuki, Ayane Sakura (young)[3] (Japanese); Adam Gibbs[4][8] (English)
Hiroomi is a third-year high school student who is also Mitsuki's brother. He has black hair in a bowl-cut and wears a scarf at all times due to his supernatural powers that make him cold. He is also a member of the Literary Club. Hiroomi adores his sister Mitsuki and likes having her call him "Onii-chan", and also has a habit of teasing Akihito and affectionately calls him "Akkey". He is proficient in setting up cages or barriers that prevent youmu from entering a protected area. His supernatural abilities make him extremely sensitive to the cold which not only causes him to constantly wear a scarf and also warm his fingers in Akihito's armpits much to the latter's annoyance. His back is severely scarred due to having to restrain Akihito's youmu rampage in the past, which almost resulted in his death.

Spirit World Warriors[edit]

Shizuku Ninomiya (二ノ宮 雫, Ninomiya Shizuku)

Voiced by: Hiromi Konno (Japanese); Luci Christian[4] (English)
Akihito's mother and a Spirit World Warrior. She is constantly traveling and sends Akihito a postcard to check up on him every so often. Akihito describes her as being a "free-spirited" avant-garde thinker in addition to possessing an eccentric personality and is thus ashamed of her child-like behavior. This is shown during Akihito's elementary school's Parents' Day when she sat at a student's desk while wearing a panda costume and participated in the class.
Izumi Nase (名瀬 泉, Nase Izumi)
Voiced by: Ayako Kawasumi (Japanese); Carli Mosier[4] (English)
The eldest daughter of the Nase clan. She usually has a calm demeanor despite having a malicious undertone.

Like the rest of her clan, Izumi is proficient in setting up barriers. She possesses a type of freezing ability while her signature weapon is a dual-tipped spear. She has a past connection with Miroku and also harbors a youmu within her body—which she tries to keep from the rest of her clan.
Maya Minegishi (峰岸 舞耶, Minegishi Maya)
A silver-haired girl who was pursued during the Spirit World Warrior-slaying incidents. Her signature weapons include an automatic pistol and revolver. She also possesses the ability to suppress the power of an Interrogation Officer. She had an incident in the past with Miroku.
