Hit Mouse (ヒットマウス) is an enemy from the first Strider and most of its ports.
A small circular flying cannon which rotates and moves in a wavy line pattern while attacking its target. They come in large groups of around 5-6 units, usually floating into view from either the top or bottom of the area, and move in waves as they constantly shoot at Hiryu. They are difficult targets to eliminate, both due to their small size and constant movement, as well as their non-stop shooting spree aimed at Hiryu.
In spite of their size, they are very hard to confront. One good strategy is to crouch down near them and quickly slash at them, trying to destroy them faster than they can shoot back.
