Sylph (シルフ) is the first boss from Aleste Gaiden.
Description[]
Equipped with an accelerator and a holographic generator, he makes it look like it's separated and dazzles the enemy. The tip of the spear in his hand vibrates at high speed, and the high frequency generated by it crushes the enemy.
Details[]
This boss appears as a trio of knights wearing purple armor and carrying spears. They appear at a random place in the screen, moving down then horizontally in the direction of the player, before disappearing and looping their pattern.
