Aliasing pikaslut → ketsueki_(character)
Link to alias

Reason:

Ketsueki is the character within the PikaSlut suit.

EDIT: The tag alias pikaslut -> ketsueki_(character) (forum #219831) has been approved by @Rainbow_Dash.

-1, because of Tag What You See: if you only see Pikaslut, you only tag Pikaslut. Vice versa for Ketsueki. Knowing that the character is in the suit is Tag What You Know, and we try to avoid that as much as possible.

And even then, what if another character is wearing the suit?

I believe the distinctive features of the suit (particularly the caution-striped cock) make it unique enough.
