Description
Karasu is a central protagonist in the anime Noein: To Your Other Self. He is identified as the twenty-seven-year-old version of the twelve-year-old boy Yū Gotō, hailing from the future timelinespace of La'cryma. The name Karasu is the Japanese word for crow.

In terms of background and personality, Karasu is a member of La'cryma’s elite military force known as the Dragon Knights. His personality stands in stark contrast to his younger self, Yū. While Yū is portrayed as hesitant, insecure, and uncertain about his future, Karasu is a hardened, no-nonsense soldier who is decisive and direct. He is depicted as a "total badass" who does not hesitate to express his disdain for what he perceives as weakness, particularly when confronting his own past self. His demeanor is shaped by the harsh realities of a pan-dimensional war that has ravaged his future world, giving him a grim and pragmatic outlook.

Karasu's primary motivation is the protection of a twelve-year-old girl named Haruka, who is believed by La'cryma to be the Dragon Torque, a mysterious object key to saving their reality from the invading dimension of Shangri-La. While his superiors intend to use or sacrifice Haruka for the survival of La'cryma, Karasu makes the pivotal decision to betray his orders and his home dimension to protect her instead. This vow of protection becomes the driving force behind his actions throughout the story. He travels across space and time to find Haruka in her own present timeline, dedicated to shielding her from those who would use her as a tool.

Karasu’s role in the story is multifaceted. He serves as a guardian to Haruka, a rival to his younger self Yū, and a former ally turned adversary to the other Dragon Knights. His presence is the primary link between the everyday world of the protagonists and the war-torn future of La'cryma. His key relationships are intensely personal and complex. His dynamic with Haruka is one of fierce loyalty and protection. His relationship with Yū is particularly fraught; Karasu confronts the boy directly, berating him for being weak and lacking resolve, essentially acting as a reflection of the man Yū could become if he endures and grows through his trials. Karasu also has significant ties to his comrades in the Dragon Cavalry, such as Atori, whose love for him turns to hatred when Karasu is perceived as a traitor. These relationships are integral to the development of his character, as his singular focus on protecting Haruka forces him to sever ties with his own past and people.

Regarding his development, Karasu undergoes a notable evolution from a soldier following orders to a self-determined individual acting on personal conviction. In the future of La'cryma, he was a member of a collective fighting for survival. By choosing to protect Haruka rather than deliver her to the military council, he rejects the dehumanizing logic of his superiors and reclaims his own identity separate from the role of a Dragon Knight. This journey highlights themes of free will and the ability to choose a different path from the one dictated by one's circumstances.

Karasu possesses a range of notable abilities as a Dragon Knight. He can travel across dimensions using a process that involves connecting his body to his point of origin with "life-lines". In combat, he wields bizarre and powerful superhuman abilities, which manifest as holographic displays and energy projections that emerge from his body. He engages in intense and spectacular battles with other super-powered beings from both La'cryma and Shangri-La, using these abilities to fight off entire groups of enemies on his own to protect Haruka.
