Shinjiro Hohoemi

Shinjiro Hohoemi also known as the villain Mr. Smiley (ミスター・スマイリー) is the main antagonist in the OVA Laugh! As if you are in Hell.

Personality
Shinjiro is a passionate artist who aspires to share his work with others, though after failing to get into an art school and receive the recognition he desired, he eventually resorted to vandalism and villainy: graffitiing walls to portray his artwork. He is not malicious, only using his Quirk to deter anyone who tries to stop him, such as the Police Force and Pro Heroes, before making a getaway.

He is recognised by Izuku Midoriya as a person who has faced rejection and is chasing after his dream however he can, even if it landed him on the wrong path. When confronted by Izuku, who reached out and empathised with him, Shinjiro understood his mistakes, believing that he was trying to prove his critics wrong but realizing that he was truly just running away from his problems.

While he has no desire to be a Hero and admits that he isn't one for fighting, Shinjiro also proves to be very brave. When a group of dangerous villains proceeded to rob the commercial building he was in, endangering innocent lives and also shooting up his artwork, Shinjiro stepped in and used his Quirk to help stop them. He is also repentant after seeing his flaws, willing to surrender himself so he could atone for his misdeeds and then continue pursuing art the right way.

Quirk
Smile (スマイル): Shinjiro's Quirk allows him to force other people to laugh uncontrollably. He activates his Quirk by showing them his teeth, it also works if his teeth are seen in a mirror or video, as long as they are seen in real time. Victims of this power will be under its effect for two hours.

Equipment
Projector: Shinjiro carries a small spherical holographic projector that he can throw like a ball. It projects an image of his face to make people fall victim to his Quirk.

Brushes: The two brushes Shinjiro carries on his hat allows him to paint whatever kind of drawing he wants in whatever color in a matter of seconds.
