When he arrives at Seiryo High School in Shizuoka, he tries to stay unnoticed but soon finds himself caught in conflicts and bullying that threaten to shatter his already fragile confidence.
With few friends and many enemies, Yami must decide whether to remain the invisible shadow he has always been or to fight to emerge from the darkness and claim his place in the world. Amid betrayals and challenges, he will discover that true strength lies not only in fists but in the courage to face himself.
