Terunosuke Miyamoto

Terunosuke Miyamoto appears in Part IV: Diamond is Unbreakable as the central antagonist of the arc Enigma Boy.

A new Stand user, he attacks Josuke in a fight also featuring Yuya and Koichi.

Appearance
Terunosuke is a man of average height and slim build. He has skin of medium tone, light eyes; and light hair in a criss-cross on his crown, framing his face and curling upwards at its ends.

He wears a long, light coat closed to the end of his chest. Underneath is a black top and fitted black pants. The inside of his coat has printed at the bottom the word "ENIGMA".

Abilities
Terunosuke's Stand is Enigma, empowered when Terunosuke identifies a target's idiosyncratic, unconscious reaction when afraid. He can then capture them in a piece of paper. When the paper is folded, the target is trapped. He can use it on objects without any condition.

Terunosuke is creative and skilled in eliciting fear.

Personality
Terunosuke is obsessed with fear. He tells Josuke the only reason he attacked was because he wanted to see their sign of fear. He sees people as objects, as when he kept a taxi driver trapped for later use.

When he is afraid, Terunosuke closes one of his eyes, and when very afraid, he closes both of them.

History
Terunosuke's Stand was given to him by Yoshihiro Kira, who stabbed him with the Arrow and gave him instructions to target Koichi Hirose. While Koichi was walking home from school, Terunosuke jumped in front of him and screamed, scaring the boy into showing his fear sign, trapped him with Enigma. He also invaded Tomoko Higashikata's house and turned her into a paper with his Stand.

Enigma Boy
Using the school bag Koichi left behind, Josuke Higashikata is able to find him with the help of Yuuya Fungami and his heightened sense of smell.

Terunosuke confronts the two at the spot where Koichi's bag was found, before casually turning his back on both of them. Josuke tries to grab him, only to turn him around and be met with his own mother (whom Terunosuke had previously kidnapped). Terunosuke had freed her from the paper she was trapped in and sealed himself inside of it. After failing to scare Josuke with a surprising gunshot, Terunosuke reveals himself and stepps out of the paper he had hidden in. He explains his Stand and taunts Josuke, who attacks instantly, only for Terunosuke to evade by sealing himself within the paper. Terunosuke then throws the paper containing Koichi into the street, and Josuke (scared by the realization his friend is in dire peril) shows his sign of fear. Enigma activates, sealing Josuke within paper and leaving Terunosuke victorious.

Collecting Josuke, Terunosuke tells Yuuya he will spare him since he did not help Josuke and Yoshihiro did not tell him to kill Yuuya. Terunosuke summons a taxi cab and driver he had sealed, and begins to take his leave, only for Yuuya to have a change of heart and attack him with Highway Star. Terunosuke slams the opened door and tells the driver to go faster, evading Highway Star for a moment before he decides to go on the offensive.



Yuuya finds the taxi stopped at an intersection, Highway Star standing on top of it. Inside there is nothing but closed papers and the scents of everyone inside. Willingly walking into the trap, Yuuya begins to open papers cautiously, triggering fire, scorpions, a bottle of acid, electricity, and even a paper shredder that traps two other papers inside of it. Finally, unable to stop the shredder, Yuuya makes the fatal mistake of showing his sign of fear, triggering Enigma while Terunosuke shows himself at last.

At the last moment, Yuuya reveals he was grabbing Josuke's and Koichi's paper as he was sealed, locking them together. This effect causes their paper to be opened as he is sealed, and Josuke quickly defeats Terunosuke. Crazy Diamond breaks him apart and restores him at the same time as his own shredded papers, turning him into a book which is then donated to the restricted section of a library. It is rumored you can hear Terunosuke's voice coming out of it.

The Book: 4th Another Day
(The information below derives from a Light Novel not written by Araki. As such, it may or may not be consideredcanon.)

It is revealed that the book Terunosuke turned into had in its pages a bunch of words from shredded paper with no meaning, although people believe there is an unknown meaning in it. Terunosuke still has a human consciousness and ocassionally asks for help. He became known as the bizarre book, rumors saying the moaning coming from it was from an old employer of the library. Chiho Futaba tried to find it with Takuma Hasumi, who memorized many books in his mind, to get inspiration for her novel, but was unable to find it and gave up.
