In Flames (BNHA)

"Nee-san! Nee-san!" Katsuki's soft childish voice sounded from my bedroom doorway as I was sitting at my desk trying to plot out my busy academic schedule. I was the captain of the music club, the swim team, Vice President of the student council and was involved in many other extra curriculars. Closing my planner, I turned to the doorway with a smile to find my four-year-old brother, Katsuki, standing in the doorway with a big grin plastered on his face.
"What is it, Kacchan?" I gave him my undivided attention, no matter how busy I was with my studies or extra curriculars I always tried to make time for him.
"Look what I can do!" He held his hands out palms facing upward and concentrated. Sweat beaded into the palm of his hand and turned into tiny explosions in his palms.
"That's amazing Kacchan!" I scooped him up into my arms and spun him around the room causing him to giggle. "You're going to be the best hero, one day." I ruffled his dusty blonde hair as I set him on his feet.
"I can start now." He grinned.
"Oh yeah?" I smiled.
"Mhm, I'll start by keeping Nee-san safe." He beamed.
I leaned forward and kissed him on the cheek, "With you as my protector, I'll always be safe."
