All the Hashiras had different tests they would put the demon slayers on for getting them to practice their best ability.This time it was the ability of hearing.The kamaboko squad participated in it along with other demon slayers.The hashiras all attended the test and were at the side witnessing.The Sound Hashira, Uzui Tengen,will drop a few coins on the ground and blindfolded participants will have to guess the number in total.They are right now standing in a line. (You're Zenitsu and a male.)
