Even though it's so overdone over the decades, but I still find scifi stories that do the quantum this and quantum that better than this ridiculousness where the MC can do and make whatever he wants by adding a "clock" in front of it. What was even the point of giving him a clearly time related skill when he just uses a clock sword, clock water cutter, clock shield, clock explosion, and clock whatever? I feel like the original author of this story isn't among the sharpest light novel authors in Japan.
