Place this clip at the exact cut where you appear on screen, then follow it with the ara ara sound for a second greeting beat. For a lighter sequence, lead into it with the pop sound effect so the entrance reads as staged without extra dialogue underneath.
About this sound
A short Japanese voice clip lasting just under two seconds, a female voice delivers the line meaning sorry to keep you waiting, lady. It feels playful and theatrically polite, like a confident entrance that turns a late arrival into a joke. The clip is shared as a Deltarune Chapter 5 spoiler moment.
