A spin-off of the popular visual novel "Steins;Gate," it takes place in a tranquil world line where Okabe has the chance to build romantic relationships with all the key characters from the original story: Kurisu Makise, Mayuri Shiina, Moeka Kiryū, Faris, Amane Suzuha, and Ruka Urushibara. Okabe finds himself in the Delta world line (>3% divergence) after performing multiple experiments using the D-mail. When he regains consciousness, he discovers the lab members getting ready for a party, and due to the constant experimentation, the Future Gadget Laboratory's electricity bill has skyrocketed. To cover the costs, Okabe takes on a part-time job as a waiter and decides to sell the latest Future Gadget. (Partially adapted from the Steins;Gate wiki).
After multiple D-mail attempts, Okarin finds himself in a timeline with a 3% world line deviation. Before he can process it, Kurisu and the rest of the team are already assembled, busily preparing for a banquet. In this new reality, a brand-new device has been developed, but the group is dealing with some unexpected issues. Their constant experimentation has drained their funds, leaving them unable to pay the electricity bill. What will this new gadget be able to do for them? This game is a romantic comedy filled with sweet and heartfelt moments, set in a world where 99% is science and 1% is pure fantasy.
