人间失格

「我度过了羞耻很多的一生。」

因医疗革命而克服了“死亡”的昭和111年的东京——。

人类由体内的“纳米机器”与通过“网络”管理纳米机器的“S.H.E.L.L.”体制的支配下，得到了不会患病、不需疗伤、确定有120岁的寿命、无病长寿的保证。然而，在这极致的社会系统之下，国家诞生了诸样的扭曲。无法掩埋的经济差距、因不死而产生的颓废伦理观、重度环境污染。以及脱离S.H.E.L.L.网络后化为异形的“HUMAN LOST现象”。日本在文明的再生与崩坏的两种可能性之间剧烈晃荡着。

大气污染严重的外部环状16号线之外——壹陆。沉溺于药物之中、过着怠惰的生活的大庭叶藏，某一日，与和暴走族集团共行的谜之男子·堀木正雄一同参加了对特权阶级所居住的内部环状7号线内的突击行动，卷入了激烈的斗争之中。在那里，遭遇了HUMAN LOST化的异形体——“丧失体”的叶藏，被所属于抗击丧失体机关“H.I.L.A.M”的有着不可思议的力量的少女·柊美子所救下，并得知了自己也拥有着与他人不同的力量——。

堕落与死。生与希望。男子被命运所戏弄、撕裂了胸膛、叫喊着。

愤怒、悲伤、同情——皆被绝望所吞没，流着血泪，大庭叶藏化为了“恶鬼”。

你，是人间合格、抑或是人间失格——

"Mine has been a life of much shame."

Tokyo, 2036 (Showa year 111): a revolution in medical treatment has conquered death...

By means of internal nanomachines and the "S.H.E.L.L." system whose network controls them, human beings suffer no diseases, require no treatment for injuries, and are guaranteed a 120-year lifespan, free from illness. Yet this consummate social system warps the Japanese nation in a host of ways: unresolved economic disparities, ethical decadence resulting from deathlessness, grave environmental pollution, and the "Human Lost" phenomenon, in which people themselves, disconnected from the S.H.E.L.L. network, become malformed. Japan teeters wildly between two potential futures: civilization's restoration or its destruction.

Atmospheric pollution suffuses "Route 16" in the Outside—the area outside the Route 16 beltway. Youzou Oba, who lives an idle, drug-saturated life, joins Masao Horiki, a mysterious man who associates with the drag-racing gangs, on an incursion Inside—the area within the Route 7 loop where the privileged class lives—only to be embroiled in a violent struggle. When he encounters a malformed sufferer of the Human Lost phenomenon, a "Lost," Youzou's life is saved by Yoshiko Hiiragi, a girl of mysterious abilities who belongs to the anti-Lost agency H.I.L.A.M., and he discovers that he himself also possesses extraordinary powers...

Degradation and death. Life and hope. Buffeted by fate, a man tears himself apart and cries out. Rage. Sorrow. Pathos. Consumed by despair and bitter tears, Youzou Oba is himself transformed into a demon. A human lost... or a human who can find himself?
