And soon AFO regret letting Sayumi watch Frozen. She always watch it over and over again. He became irritated and decide to take the DVD player and now explain Sayumi's boredom.
"Let it go! Let it go! Etc..." While do what Elsa do with her hand, Sayumi copying everything. "Turn away and slam the door! I don't care what they going to say-" and without her conscious. She creating a ice wall and the ground became ice.
"The cold never bot-oof!" She slipped and Realize that she created tons of ice, there's hot ice and cold ice. Each of them has a different color with a different temperatures.
"Wow, what's going on? I've ice quirk. Amazing!"
She realize something
"But,do I have a fire quirk?"
'hmm, let's check if I have a fire quirk or not.'
She relax and try some little technique that she see dabi do to warm up his body and quirk. Also she do what endeavor do too. Yeah, she always watch endeavor fight along with other heroes and she taking note about it. About their quirk,their technique, their weakness, anything about the heroes. She thinks that when she has a quirk,she will examine the technique and try creating one her own.
Swosh! There's fire at her hand that surprise her is she can change their color and temperatures!
"Wow, I knew it! I've fire quirk!"
'okay, let's melt the ice down. Since my ice have a different temperatures, I'll melt it with opposite temperatures of it with fire.'
