Sakumi has a big heart and is a caring person, although it might not look like that at first because of how unresponsive she can be. She’s a bit ditzy and oblivious, zoning out from time to time and getting lost in her own world. It’s also hard to follow her whenever she tries to explain her talent as the Ultimate Alchemist. Described to be a modern-day apothecary, Sakumi’s talents earned her a spot at Hope’s Peak Academy where she tries her best to bond with the others.
