This is not about the Japanese band (which, I may add, I quite fancy when they cooperate with Nagi), but about a real supercell that descended on France, my country.
This is the first time in my life I see something akin, I was very scared. Barely a couple hours before that, I was still out, and I surely didn't expect the hail. Not your standard hail: it was like ice cubes fell down from the sky as though fired by machine guns. No casualties are reported yet, but danger is certainly here: vineyards in affected regions are entirely destroyed; roofs and cars were damaged to various extents.

This was quite awe-inspiring. I think the supercells are planned to occur all week-- I'm required to go outside all week. Wish me luck in France.
