Summary
From the egg comes Echoes, and after getting his mother and sister out of the family room, Koichi latches Echoes onto Tamami. Despite Tamami's threats and protests, Koichi stand his ground and orders him to release his family, having Echoes punch Tamami. However Tamami isn't injured in the slightest, and after several other punches from Koichi's Stand, understand that Echoes is incredibly weak. He then grabs Koichi by the collar to beat him, but words have appeared on his cheek. It is the onomatopea "Blam" Echoes has planted on Tamami, and the latter begins to hear violent noises, with increasing loudness. He also looks at his arm and sees the onomatopea "Vlam", which he hears too, forming a cacophony which is driving Tamami crazy. When he tries to punch Koichi, Echoes plants another onomatopea on his back, increasing further the noise he hears.
