Laser Maiden 2 is an unlockable mini game that will appear in the "Extra Mode" menu after a few game clears in the normal game mode. (Most likely after you unlock all the characters/ships, though the number has yet to be determined how many.)
Once the game mode is unlocked, you control Hayate where the only attack is used with the A button to fire once at a time, Galaxian style. You can also scroll to the edges of the screen to go to the other side. The objective is to earn 30,000 points. The game will be over if you either take a hit from enemy fire, or if you touch the enemy's hitbox if they dive straight to the ground with no way of escape (though you can destroy them from a specific flashing enemy, though the odds of having that happen are random at best.)
Each enemy defeated normally is 100 points, but if you shoot them while they're floating after defeat will produce a laser which grants you 500 points if other enemies are in contact from it. The difficulty will ramp up the longer you survive, so getting 500 points each time is the key to getting the achievement. (This Guide is Provided by Neostraycat, only the video is my own)
