The glass cracking-like crushed sounds came from the barrier magic Suzu had chanted beforehand; similar to how Shizuku took maximum caution. It was something she did immediately when she instinctively sensed the crisis. The location was at the rear side of the party. She didn’t feel the “existences” there, but she somehow used the barrier to not only envelop Shizuku and Nagayama, but also everyone on the rear. It was something she did instinctively which could also be said that it was due to her experience. Her action was extremely correct. Without Suzu’s barrier, the third blurred space would mercilessly cut up Nagayama and other party members.
