Chaser

are recurring traps in.

Characteristics
NaN Chasers are similar to NaN Blade Traps in that they will chase Series: if he crosses their path in one of the four cardinal directions. They move slower than NaN Blade Traps, however, and will not return to their original position upon reaching a wall. They will instead stop at their new position, and "chase" Series: from there. NaN Chasers are often found in narrow corridors where they are more difficult to dodge.
