One of the best action VNs I've ever read, when it puts its foot on the gas, it really doesn't let up. There's some finicky things with it being oldge with heavy animations however, may need to download additional video codex if you have a newer machine to get them to run properly. Romance tends to be a little light, but they balance the dark and gritty bits with some moege tropes that make it all easy to read and digest even when the going gets tough. If you don't mind a little troubleshooting and want a VN with a heavy dose of giant monsters and robots fighting, then this is one of the best VNs out there for it.

Came for the story stayed for the weirdness but it does got some gore lots less then safe content and not much nsfw would recommend if you want a violent story with some sex in it.
