Concealment Release: Soundproof

This technique allows Yasu to dampen any noise he makes. This can extend past him to include nearby objects or people. However, it begins to fail if used on many people at once, or to silence very loud sounds. The magnitude of sound made from something like an explosion can only be lessened and not covered up completely.

As an information broker, Yasu uses this ability to get past defenses and acquire new data. From his footsteps to doors closing to things falling over, Yasu can quiet the various sounds that would get others caught.
