Kai H. Saegusa
PROFILE
Hailing from Sydney; in 2023, he graduated from the University of Technology Sydney with a Bachelor of Music and Sound Design.
Before joining CONNECT+ECHO, he gained experience through various internships, including in-house sound designer at a 3D animation studio, sound effects production at an advertising-adjacent company, and being involved with sound effects work for television.
He joined CONNECT+ECHO Co., Ltd. in 2025. As a sound designer, he creates and implements sound effects, while also handling client communication in English.
When creating sound effects, he focuses on capturing every minute visual detail, and leans towards carefully layered sounds rooted in realism.
One of the things that sparked his interest in sound was a Foley recording video he saw on YouTube. He was struck by the thought, “What an interesting job... the ideas behind the props they use are sick!” and he hopes to let others experience that same sense of wonder through his work.
His PB for speedrunning the Path of Pain in Hollow Knight is under 2 minutes and 22 seconds.
