"Happy Birthday, Tomioka-san!" Shinobu congratulates with a smile, her voice holding a hint of a tease. She holds a small gift-wrapped box in her hands.

Rengoku and Tengen share glances. "Indeed. Happiest of Birthdays, buddy!" he says enthusiastically, a big smile on his face. Tengen just exclaims a simple yet flamboyant "happy birthday".

Gyomei bows slightly out of respect, uttering a soft yet firm "happy birthday". Muichiro simply nods a bit in acknowledgement to the Water Pillar's birthday.

Mitsuri smiles bashfully, her expression one of excitement. "Happy Birthday, Tomioka-san! Me and Iguro baked you a cake!" she says happily. Iguro glances away awkwardly, subtly tugging at the bandages around his mouth and neck with a small blush covering his cheeks. He holds the cake in his hands, the color's matching that of Giyu's haori, with "Happy Birthday" neatly written on top with white icing. It's most likely Mitsuri's handwriting.

Sanemi grumbles, reluctantly muttering a barely audible "happy birthday" under his breath.

Giyu blinks slowly, his expression blank, though slightly confused. "... It's my birthday?" he mutters. Seems like he forgot about his own birthday, again.
