This is Kouta Kayano, your generic male friend to Itsuki Tachibana. While he’s somewhat plain-looking, Kouta is actually playing Phantasy Star Online 2…
…as a Deuman Fighter named Koa. Man, I feel that I’m out of the loop somewhat that PSO2 has nine classes compared to just three or four back in PSO or PSU!
Anyways, this episode focuses on making a party and role-playing your character, as Koa shows that he’s cool and somewhat hot-blooded!
On the other hand, there’s a new character introduced named Yutaka Sasaki. On the surface, Yu-chan is a meek student at Seiga Academy…
But when play PSO2, he becomes a different character named Musashi. And here’s the thing, Musashi is a troll player who either refused to cooperate or mess up their game!
Then again, seems that our generic protagonist Itsuki just out-trolled Musashi by carelessly revealing his real-life identity in front of other players!
And yes, Musa- I mean Yu-chan couldn’t believe it that his alter-ego got exposed badly, so much that Yutaka refused to go out to his dorm!
Fortunately, Itsuki convinced him to get out from his safe zone and try to befriend people. I mean, he wants to make friends with Yu-chan to begin with.
But in any case, Yuta- I mean Musashi became one of Itsuki’s allies!
And now, let’s end this episode where Rina Izumi revealed to Itsuki Tachibana that she’s playing PSO2 as SORO.
That’s right, she’s playing the aloof CAST Ranger who wanted to help the vice president to get better at playing for the weekly report!
As for Itsuki, he’s not surprised at all as he figured it out her real identity before Rina-chan told him about it.
On the other hand, is it me or Itsuki is becoming an all-knowing troll protagonist lately? Then again, he’s still a generic lead character to me!

He still feels like a generic lead. But at least he is not dense and figured out she was SORO.
