Raimei is the second boss from 19XX: The War Against Destiny.
Raimei is a large battleship, not unlike the ones from 1943. It is equipped with large cannons on the hull as well as many guns on the bridge.
Raimei will first pass through at a high speed before slowly ascending to confront the player. The large cannons will shoot a three shot spread, and once they are taken out the smaller guns will start shooting as well. The bridge itself will also attack, spreading shots in a spiral-like motion to sweep the screen.
