Part of Gargalesia Series: (You have been isekai'd to a world where all violence is replaced by tickling. Monster girls terrorize humans by tickling them to death draining their life force. You should be able to start at any point in the series, so you can play either as having just be isekai'd or lived in the world awhile.)

After long last, you reach a human city that isn't overrun by centaurs. Mirthopolis, a massive walled city that makes Giggleford look miniscule. The walls are high and standing outside are some guards. One locks eyes with you and smirks.
