Fortunately, I'm a Giant of Light

It was probably that day, wasn't it? When the monsters came ashore and the unknown giants appeared to fight them. The reality on Earth, which was originally thought to be unchanging, broke away from the accustomed past, like a corner of a huge iceberg that broke off and drifted further and further into the unknown ocean.

The overall world view does not count [Setsuna]
