Type-C, 2nd midboss. Place your option on top of the boss, hold down the autofire button and tap the laser button to produce lots of energy items fast (you'll notice if you hit 72 pieces when your option can't hold any more energy in place and they start to leave the screen), then just graze the midboss' bullets. His patterns should be dense enough to make the energy items grow to maximum size before they disappear.
