Shinkun

A Shinkun (真紅) is a dark, spiritual being that exists within The Drillimation Universe, usually in the form of a humanoid or youkai. Shinkuns can exist in other forms too, such as Pacteria or an animal.

Shinkuns are generally difficult to kill due to their ghostly abilities, and the general methods of killing them is the use of sealing rituals such as a crucifix, ofuda, or gohei. Alternatively, people who are invincible using a Lucky Star can kill them instantly.

Crystal Island
Shinkuns started appearing regularly in the Crystal Island anime, with them usually created by King Empty Jay in an attempt to wipe out Driller and his friends. One time at the end of Driller's second year, several students from Mineplex All Boys High School disguised themselves as Shinkuns to terrorize Minecraftia High School, which led to the Mineplex All Boys High School Send Off Incident.

Mr. Driller Ace: The Wonderful Pacteria
Shinkuns made their first appearance in The Drillimation Series in the Super Nintendo-exclusive Mr. Driller Ace: The Wonderful Pacteria in 1993. Shinkun Pacteria were the first Shinkun species ever created, and were created by Dr. Manhole to prevent Susumu from rescuing Konata.

Lucky Star series
Shinkuns made their debut in the 1994 Lucky Star game Lucky Star Bloodlines as a regular enemy. Their main AI is shooting worm-like bullets at the player like in Touhou 5: Mystic Square.
