Hideyoshi Nagachika

Hideyoshi Nagachika (永近 英良, Nagachika Hideyoshi), also known as Hide (ヒデ), is a normal human and the best friend of Ken Kaneki and Shouta's adoptive maternal uncle.

He attended Kamii University as a freshman and, later, sophomore. While there, he was studying Foreign Language Studies — majoring in English — at the Department of International Studies.

At a certain point, he started working part-time at the CCG, and soon became an investigation assistant helping both Koutarou Amon and Akira Mado.

He disappeared during the Owl Suppression Operation, and later resurfaced under the identity of Scarecrow (スケアクロウ, Sukeakurō). With the disguise of a low-rated Ghoul, he lingered on the fringes of several major operations and meddled without revealing his true nature or goals. He was mentioned that he died mysteriously by a 'Ghoul Hunter'.

Appearance
Hideyoshi is a young man of average height with short, messy, dirty blonde hair with dark roots and olive eyes. He tends to wear bright colored clothes that consist of a yellow varsity jacket and green shorts. Because of his love for music, he usually wears a pair of headphones around his neck.

Several years later, he continues to wear casual clothing and has cut his hair back into the short style he wore during college. When not wearing his Scarecrow costume, he opts to wear a scarf to conceal the lower half of his face and his throat. Underneath, heavy scarring covers his face from just above his upper lip and extending down to his left clavicle. The flesh has been almost completely stripped from his lower face, exposing his teeth and leaving very little to cover the bone structure. The Zygomaticus major muscle is missing, leaving a large hole in his left cheek. The damage continues down his throat, with a vocal prosthesis surgically implanted into his neck and several areas where the skin has been torn away. Across his left clavicle, there is exposed muscle tissue and evidence of the skin being stripped away.

Personality
Most of the time, Hide has a carefree attitude, always joyful and friendly, which greatly annoyed Nishio. He doesn’t seem to share relationships with people beside Kaneki, despite his appearance. He commented to Kaneki that even though he hung out with Nishiki, he thought he was poisonous, and that he might even hate him. Hide is also incredibly observant and can figure things out about people in an almost Sherlock-like manner. He also becomes interested in things and works hard on them until he finds something else that interests him. Hide claims to have a habit of pretending to be a detective by putting tracking devices on suspicious people and notifying the authorities if his intuitions turn out to be right (however, the "hobby" part of it is most likely a lie he made up to hide his true motive from the CCG, which was to find clues about Kaneki's whereabouts).

Hide also has a very "determined" behavior. When he's set goals or decisions, he'll stick to them to the very end.

He looks out for his friend Kaneki, encouraging him about many things and worrying when he doesn't return his calls. In some ways, Hide is also the opposite of Kaneki, as he is the outgoing type for festivals while Kaneki, more the introverted type, does not like these kinds of events.

Though he is loud and outspoken, Hide is usually found keeping most of his concerns to himself in order to not trouble those surrounding him.

Just like his best friend, Hide has a habit of placing his hand on his face when he is nervous or is lying.

Ken Kaneki
In Tokyo Ghoul, Kaneki calls Hideyoshi by the nickname "Hide," and they have been best friends since childhood. Hide seems to care greatly about Kaneki and had been watching him carefully after the incident with Rize. If Kaneki was in trouble or danger, he would do his best to support him. He cares for Kaneki immensely and did not falter to help him even after finding out about Kaneki's transformation into a ghoul. When asked by Amon why he was willing to go so far for Kaneki, Hide outright declared that he loved Kaneki, and he didn't need any reason other than that.

Touka Kirishima
Although they do not know each other well, Hide is on friendly terms with Touka, and thinks she is cute. At Kamii, he spoke briefly about his and Kaneki's past, and gave her a tip on how to tell when Kaneki was hiding something. Later on in the series, Hide asks Touka about her relationship with Kaneki.

Koutarou Amon
Hide worked under Amon and Akira when he joined the CCG. Amon sometimes chided Hide when he was socializing or not working, a small clash between Hide's carefree disposition and Amon's work-orientated mentality.

Akira Mado
Hide worked under Amon and Akira when he joined the CCG. Akira seemed to have been suspicious of Hide, as she noted that he was strangely perceptive when asked about the mother and daughter ghouls' relationship to the Rabbit ghoul.
