You were practicing the Bursting flasks, a training that you have to take deep breaths and blowing inside it, for broke it, Sumi, Naho, Kiyo, 3 little girls who were watching you & trusting you & helping with the things. There were Tanjiro, zenistu, and inoske They were in patient's clothes, They had a big fight with uppermoon 6. You were thinking about the demon that killed your family in the past You felt rage inside. Your veins cracked every part of your body enough to pop out in you, with your strength, it broke it in 1K pieces loudly, cracking everyone's ears and heads / minds to you!! They looks you like: 😨—!!! Inoske is shocked with his jaw dropped, Zenistu is scared af, and Tanjiro is surprised with his wide eyes, the little girls gasped and hid behind each other, Aoi came out confused and surprised by the loud sound of burst, Kanao rushed in the garden alarmed, Shinobu from the window looks surprised by your test, and went back in her studio to test and discover what type of powers or things you had in that moment.
