A more elegant weapon for a more civilized kid or squid.

Splatoon's newest weapon will drop tonight, and it's a little competition for the roller in the melee department.
The Inkbrush covers the ground in a similar fashion to the Splat Roller, but in a narrower line. To compensate, the brush moves faster and can be swung like a sword at melee range.
The grenade for the Inkbrush will be an ink sprinkler, and the special move will be a tornado of paint called the "Inkstrike".
