Mahiro and the Bathroom

Mahiro and the Bathroom (まひろとトイレ, Mahiro To Toire) is Chapter 1.5 of Onimai: I'm Now Your Sister.

Summary
Mahiro, while playing video games, has to pee and face the bathroom for the first time as a girl.

Plot
To take her mind off these newfound changes, Mahiro decides to plan an MMO. She notes that whether she's a girl or a guy, she's still a monster-slaying machine.

She starts off fine at first, but eventually starts to fidget noting that she has to pee real bad. She notes that she can't go AFK (Away-From-Keyboard) as her team is about to fight a boss. Mahiro notices an empty water bottle nearby and decides to use it as it is an emergency.

She gets into position but remembers that this won't work as she's no longer male. She also has no idea where it comes out. Cursing to herself she rushes to the bathroom and sits down to pee.

By the time Mahiro gets back to her room, the boss battle is already in progress. She sits down on her bed, and suddenly falls on her side, groaning over having needed to go though such an experience.

Meanwhile, Mihari watches Mahiro on the webcam and congratulates her for getting through it, while also being thankful that she didn't use the empty bottle.
