Miu Iruma is the Ultimate Inventor from Danganronpa V3: Killing Harmony. She's a participant in the Killing School Semester at the Ultimate Academy for Gifted Juveniles.

She's a loud, over-the-top, super confident (and often arrogant) girl genius who loves bragging about her "gorgeous looks and golden brain." Her inventions are wild and advanced—she's the one who created things like eye-drop contact lenses that became a huge commercial hit. Miu's personality is brash, vulgar, and extremely perverted; she's constantly throwing out crude insults, sexual innuendos, and trash-talking everyone around her (especially calling people virgins or mocking their appearances). Despite the tough, obnoxious exterior, she has a hidden insecure and vulnerable side that shows up in quieter moments.

In the story, she starts off helpful (in her own abrasive way) by building gadgets for the group, but her arc takes some dark turns involving manipulation, betrayal, and tragedy. She's one of the most memorable and polarizing characters in the game thanks to her unfiltered energy and complex layers.
