This episode also marks the branching point for Feyris' ending in the VN. Here's the video. This ending is also a bit depressing...

Spoiler for Feyris' Ending Summary:

Okarin decides not to send the D-Mail because he did not want to sacrifice anyone else’s happiness after Suzuha. He tries to think of an alternative way to retrieve the IBN5100 and learns that Feyris’ father had sold the retro PC for enough money to start his own business. Perhaps Feyris can send a D-Mail to convince her father to sell the rest of his PC collection instead of the IBN5100.

The D-Mail is sent, Akiba is back to a place filled with Otaku stores. He goes to Suzuha’s home to find the Divergence Meter and discovers the value had decreased. Not only that, the Mirai Gadgets Lab had ceased to exist. He goes to visit the May Queen maid cafe and finds both Mayuri and Daru there but neither of them knew Okarin. Feyris was now his girlfriend. In this timeline, they met in a small Rainet shop where they had a fierce battle together. They decided to join forces for the grand championship and Feyris fell in love with him.

Mirai Gadgets’ existence is erased, Mayuri is saved. Only Feyris knows who Okarin is and they continue to be lovers.
