The graduation trip of the Undersea Train

When I boarded a sightseeing train with my childhood friend Hengsheng, my friend Yuguang, and classmates, I joined a trip organized by Shiyue, heir to the conglomerate. Train derailments, tunnel ruptures, and seawater flooding occur one after another, while recurring deaths indicate that this journey has fallen into an abnormal time loop.

Companions and organizers

Wushi, Hengsheng, and Yuguang grew up together from childhood. Hengsheng longs for an ordinary and happy family, while Yuguang, a key player on the basketball team, pays close attention to their subtle relationship. Se Yue seems impeccable, but rumors circulate at the school that she is conducting dangerous experiments; Rumors do not equal proven truth.

Narrative and production

The work uses a multi-ending structure, paralleling the sci-fi setting of time loops with in-car investigations and romantic relationships. Xiaolu was responsible for the script, Chunyu for planning, Yu Shiliang for the original artwork, Zhan Lan Music Studio for the music, and Xue Nan to participate in the singing.

Travel partners and organizers

Wushi was childhood friends with Hengsheng and Yuguang, and together they joined the undersea train's graduation trip called "Time Journey." The travel organizer, Setsuki, comes from a chaebol family, and her personal maid is also on the train. Disasters and time cycles constantly change the relationships among companions.

Production and soundtrack

The script was by Xiaolu, the project by Chunyu, with programming and direction by Liang Long, Yushi Liang as the main art director, and Moko in charge of SD art. Music credited to Azure Music Studio, with Xue Nan performed by the game page list; The soundtrack page also specifies that OP Interaction is performed by DIA and ED Rewrite by Shippo.

Original soundtrack included

The original soundtrack released on July 6, 2021, is described as having 25 tracks, and currently lists 23 tracks. Includes OP Interaction, ED Rewrite, and ED accompaniment, with both artist and composition credited to Alex Lu.

Section 13 carriage with deadly fuel

Setsuki reveals to Wu Shi that the journey of time is actually a time machine, and the appearance of the 13th carriage indicates that someone is already using it. Reversing time requires new dead people as fuel; my time is the original fuel. The world's self-healing allows him to retain memories of reincarnation and also fixes the cause and effect of his future death; Even if the transmigrator known as S is stopped from continuing the killing, the cycle of reincarnation is not yet over.

Three redemptions in the end

In Ending 1, after a brief intersession between Gotoki and Setsuki, he still dies. In Ending 2, Wushi and Hengsheng end their cycle of reincarnation through a suicide for love. In Ending 0, he uses himself as fuel to repeatedly reverse the cycle alone, waiting for the cycle to end; The two female leads teleport his consciousness to the future, and Wushi survives and confesses to Hengsheng. Next Christmas, the five of them will return to the journey and take a group photo.

Health and character memory after reloading

Incorrect reasoning choices will deduct HP. Normal saves cannot restore lost lives, and you must restart after completing a non-BE ending. After the reincarnation narration, the process returns to the main menu, the Start button is stained with blood, and the corresponding character is displayed on the right; Starting again, the story shifts into the flashbacks of the other main characters. Among the three main endings, completing the two female leads' endings first unlocks the Ending 0 entrance. Keeping your HP at full will also unlock corresponding options.
