[Decompilation] [th05] Shinki: Pattern 1/11 The one where Shinki fires bullets in a ring, with each new ring fired at an increasing or decreasing angle, for a curved effect. The first pattern you see in the fight. At least the pattern functions are short and sweet for the most part. Part of P0190, funded by nrook.
