Terunosuke Miyamoto

Terunosuke Miyamoto is an antagonist from Part IV: Diamond is Unbreakable.

About
His stand was given to him by Yoshihiro Kira, after which Terunosuke was given the instructions to go out and target Koichi Hirose. He attacked while Koichi was walking home from school, and defeated him off screen. Using the left behind school bag, Josuke was able to find him with the help of Yuuya and his heightened sense of smell.

Terunosuke confronted the two at the spot where Koichis bag was found, before casually turning his back on both of them. Josuke tried to grab him, only to turn him around and be met with his own mother (who Terunosuke had previously kidnapped). Terunosuke accomplished this by freeing her from the paper he had trapped her in, and sealing himself inside of it. After failing to scare Josuke with a surprising gunshot, Terunosuke revealed himself and stepped 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 with in paper. Terunosuke then throws Koichi (within paper) into the street, and Josuke (scared by the realization his friend is in dire peril) shows his sign of fear. Enigma quickly 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 since Yoshihiro didn't tell him to kill Yuuya. Terunosuke summons a taxicab and driver he had sealed, and begins to take his leave, only for Yuuya to have a change of heart and attack him with the ultra fast Highway Star. Terunosuke slams the opened door and tells the driver to go faster, evading Highway Star for a moment before Terunosuke decides to go on the offensive.

Yuuya finds the taxi stopped at an intersection, Highway Star standing ontop 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 Josukes and Koichis paper as he was sealed, locking them together. This effect causes their paper to be opened as he is sealed, which results in Josuke quickly defeating 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 donated to a library.
