I was surprised to discover this unaired episode included with the BD box set release available so soon after the tenth and last episode aired last week, but here we are. Episode 10 brought everything to a nice close (or at least ellipsis, in which we can imagine Morimori and Sakura-chan getting along for many years to come); this is not necessarily a continuation of the story, just a couple of side stories involving the two.
First, Sakurai has agreed to build a new PC for Morika after her motherboard fries. That means coming to her house to set it up. The opening moments almost seem to tease Sakurai moving in with Moriko, but considering he has like five times the space, that seemed counterproductive. Before he arrives, Moriko does a comprehensive clean of her apartment, also trying and failing not to make her out-in-the-open bed look welcoming.
After meeting up with Sakurai to acquire all the kit he’ll need, he gets to work assembling and installing while Moriko makes tea. Just having Sakurai in her house and at her desk causes her to space out, spilling a little hot tea on herself. In Sakurai’s haste to ensure she’s okay, he trips and the two end up in a very compromising position against her bed.
With all that fun out of the way, Sakurai breaks out his laptop and the two play Fruits together in the same room, which is an entirely new and highly enjoyable experience, considering they can just talk to one another in person rather than use the chat. However, Sakurai gets a little overexcited and ends up asking Moriko if she’s join him on a hot springs trip; he later qualifies it by saying Koiwai will join them as a third wheel.
We don’t get the story of that hot springs trip, however; the second half of this extra episode seems completely independent of the first, as eagle-eyed viewers will notice Moriko’s playing on her old PC. She nods off in the middle of play, and wakes up in the MMO world, as herself, Morika Moriko, in a premise that echos Re:Zero and KonoSuba.
It’s fun, as Moriko is totally unequipped to fight off the giant mouse, let alone have any hope of defeating the “Demon King Koiwai” who is holding “Princess Sakura” hostage. That is, until she’s saved by her own avatar Hayashi and healed by Lily.
The two know Moriko as the “famous hero Morimori”, and join her quest, as does Fujimoto, working in the game’s version of Lawson Market under his avatar Kanbe. The only way to defeat Koiwai is to don some very revealing bikini armor, but Moriko can’t do it (though she does imagine herself in it, so we get the visual).
But because Koiwai didn’t stipulate who had to wear the armor, Sakurai dons it instead (a sight we’re spared), only to find he isn’t able to remove it. That’s when he wakes up in his apartment, having nodded off just like Moriko. A cute little side-story, if ultimately unnecessary.
