Mahou no Star Magical Emi EP23 - I'm Sorry, Mii-chan

When Misaki accidentally ruins a beloved apron that Mai made, she tells him that she hates him, and he later runs away after hearing her say that she wished he didn't exist. His disappearance causes everyone to band together and search for him across the city, and Mai blames herself for being so unforgiving. Meanwhile, Misaki wanders aimlessly, not wanting to go home and further upset his sister, who he loves.
