Synopsis
Toshikazu is one of the few who were given stand abilities by Keicho using the bow and arrow.

He had been rumored to have had an arguement with his friend the night before his friend dug out his own eyeball with a ballpoint pen. The friend's motive for doing this was unknown as he said he already had the eyball in his hand before realizing what he was doing. Apparently, the friend had been taken control of, possibly with a stand ability. This was suspicious enough for Josuke and Koichi to investigate.

After searching the school, Josuke decides to break open Toshikazu's locker. Inside he finds a strange wooden doll, whom turns out to be Toshikazu's stand, Surface. After copying Josuke's image and rendering him unable to move, Toshikazu appears from behind some lockers and explains that he wishes for Jotaro to leave town. Josuke tries to attack Surface, but is unable to do so with his stand range. Surface forces Josuke to elbow Koichi and then stab himself in the eye with a pen. Assuming he had knocked Josuke unconscious, Toshikazu and Surface make their way to meet up with Jotaro.

After calling Jotaro to meet up with them at the train station, Surface (who is disguised as Josuke) is greeted by many school girls, which seemed to have angered Toshikazu. He attempts to punch his own stand, but realizes it's made of wood, and ends up hurting himself. Surface rebukes Toshikazu for his actions since he has seemed to have taken Josuke's personality.

Toshikazu wipes the blood from his hand upon a nearby motorcyle. The owner of the motorcycle finds the smudge on his car however, and begins to insult Toshikazu. Surface comes from behind and knocks out the Motorcycle owner's friend and then grabs the owner from behind. Toshikazu pulls out a scapel and attempts to cut the man from the inside of his mouth, but is stopped when broken glass is thrown at him. Surface catches the glass and realizes that it was thrown by Josuke. Josuke is able to reform the broken glass back into a bottle removing Surface's right hand in the process. This allows Josuke and Keicho to run up ahead.

Josuke and Keicho arrive at Jotaro first, but Surface manages to take control of Josuke again. However, before he is able to attack Jotaro, the motorcycle owner and his friend from before appear and drag Toshikazu off. Josuke, having broken free of Surface's ability, destroys the wooden doll.
