Visual novel spin-off where the time-travel chaos takes a break. After D-mail experiments land protagonist Okabe in an alternate timeline, he's stuck with a mundane crisis: the lab's electricity bill is astronomical. To dig out, he and the crew try selling their latest invention while prepping for a party. The setup pivots from the original's thriller tension to slice-of-life hangouts and romantic routes with six characters—Kurisu, Mayuri, Moeka, Feiris, Suzuha, and Ruka. Each path branches into its own scenario. Expect dialogue-heavy scenes, light comedy about broke scientists, and dating sim structure instead of conspiracy puzzles. If you wanted the main story's stakes dialed to zero so you can just spend time with the cast, that's the pitch.
