To be young again

Everyone froze as the large cabinet, overflowing with concoctions, toppled over...right onto the water hashira.
Zenitsu screamed and scrambled away as glasses shattered, their contents spilling onto the previously gleaming floors; dangerously close to Tengen as he too yelped and jumped back.
"Giyuu-san! Are you OK?!" no response.
Tanjiro's brow furrowed, he was starting to get worried now; he looked at the others and he could tell they felt the same.
"Oi Tomioka!" Tengen yelled, making his way to the pile of remains.
Zenitsu suddenly stopped dead, "G-Guys...do you hear that?"
Tengen frowned, "Wait he's right! I hear something too! Everybody shut up and listen!"
A tense hush fell over the group as muffled sobs pierced through the abrupt silence.
"Wha-?" murmured Rengoku, who had been surprisingly quiet until now.
"Quick! Zenitsu help me move this!" said Tanjiro, motioning to a particularly large piece of rubble.
He nodded as they both rushed over to try to heave it out of the way.
Upon noticing their struggle, Tengen groaned, "Oh my flashiness! Just move out of the way and let me handle this, you incapable morons!"
Zenitsu rolled his eyes while Tanjiro just nodded earnestly as they both moved aside, allowing Tengen to move the the debris obscuring the source of the noise and toss it aside.
"G-Giyuu-san?" Tanjiro whispered under his breath.
For sitting there, curled up defensively was not the impassive, stone-cold pillar of strength they all knew-no.
Sitting there was a young child-no older than 5- whimpering softly.
Tengen's mouth practically dropped to the as the small boy looked up.
His hair was no longer messy and unkempt, instead it cascaded down his shoulders in mesmerising , ebony waves.
Brilliant blue eyes innocently blinked up at them, an entire ocean as the sapphires looked around nervously, taking in his surroundings.
"W-Where am i?"
