Summary
Mahiro starts playing as a female healer in an MMO game.

Plot
A ferocious dragon roars at a group of knights. One of them tells the other one to hold on as they are almost there. Out of nowhere, what appears to be Mahiro heals them.

It is revealed that Mahiro is playing an MMO game as a female healer, having fun by dropping in on unsuspecting players and then disappearing afterwards.

Mihari suddenly walks in and notes that Mahiro is on an MMO again, but also notices that she is playing as a girl character in her games now. Mahiro is startled by her sudden appearance and tells Mihari that it's not what she thinks. She claims that she isn't playing as a girl because of what has happened to her, but rather that if she's going to stare at an avatar all day it should be cute. She claims that looking at a girl is way better than some dirty, smelly guy and says that she doesn't know why anyone plays guys in video games if they have no choice. Mihari thinks to herself that it is a sensible excuse.

Mahiro pushes Mihari out of her room wondering why she keeps barging in and tells her to stay out. Mihari agrees to stay out but reminds Mahiro to remember to take breaks. Mahiro remarks that she can't believe her and sits back down.

Right before she does, she gets a whisper on screen and notes with frustration that the guys noticed her and are thanking her for the heal. They ask Mahiro if she wants to join their guild since they could really use a healer. Mahiro notes how it is much easier to play solo, but accepts since they asked nicely. She notes that if its a drag she can always quit.

Mahiro begins her life as a guild member and begins acting as the group's healer. She notes that things were awkward at first, but they started to gel once they fought as a party. Mahiro notes that this is actually pretty nice.

A few days later, the guild members sit around a virtual campfire where they boys continue to thank Mahiro for her support, which makes Mahiro blush as claims that it wasn't a big deal. One of the boys remarks that Mahiro is like their goddess, which makes Mahiro feel even better. She notes that it may be a bit much but that it is nice to be appreciated. A member of the guild, Kerori, who just joined that day tells the others not to say that as Mahiro is clearly a guy, a statement that leaves them all shocked.

The other two guys tell Kerori that he can't say that. Mahiro thinks to herself that she doesn't like him, as he only just joined the guild. Kerori claims that how Mahiro types is a dead giveaway, this shocks Mahiro who thinks to herself that she is just being polite. The other guys continue to berate Kerori, but note that he has a point as girls don't play online games that much and that cute characters are usually played by middle-aged guys. Mahiro is stunned, but remarks with a chuckle that unfortunately for them they are dead wrong.

Mahiro says that she is a real, genuine, actual girl. The other guys are in disbelief and tell her to give pics as proof or to leave, much to Mahiro's anger. They then say to at the very least hop on the voice chat, and Mahiro decides that she has to.

Mahiro asks if they can hear her, and all three guys are shocked out of their minds that they've been playing with an actual girl. They remark that her voice is so cute and ask how old she is, to which Mahiro answers that she is a teenager. The guys continue to go crazy asking where she lives and if she wants any rare items or anything. Mahiro is baffled, wondering why they are acting like this. She then realizes that it feels like she's got them eating out of the palm of her hand and that it is kind of intoxicating.

Kerori sends her another whisper apologizing for outing her, but remarks that he still wants pictures and gives his email address. Mahiro notes that even the investigator is kind of endearing in a way but that she can't believe that he is asking for pictures. Deciding that she doesn't look half bad, she decides to take some selfies of herself, even if she's not going to send them to a random stranger.

Mahiro takes one of herself, but after seeing her eroge games in the background decides to try taking them in the living room instead. Mihari catches Mahiro taking the selfie and playfully asks what she is doing. Mihari fawns over the picture and remarks that Mahiro is super cute like this. Mahiro claims that she isn't and tells Mihari that it is not what she thinks.

By the time Mahiro gets back to her computer, the guild had dissolved into infighting and disbanded. Mahiro breaks down in tears telling the guys not to fight over her.
