Oh boy. Nyaruko already had an excessively healthy libido in female form. Assuming being a male amplifies that, I hope she doesn't turn poor Mahiro's toolkit into a bloody stump. His right arm is going to be in tremendous shape either way...
What would be hilarious if they followed up on that gag next episode and had her intermittently going to the restroom so she can tickle Elmo, no matter how dire the situation.
By the way, we need more masturbation euphemisms, people. Get with the program.
