A new work from the author of 'My Senior Brother is Too Steady', welcome to enjoy it!------------------In the instant the Earth exploded, the fear of death finally transformed into physical torment, the agony of being scorched seared into the deepest recesses of Yang Ming's memory.“The universe is the abyss.”Yang Ming murmured softly among the stars.[PS: Not a game narrative; early game settings will have a complete logical explanation later in the plot. Starting anew on a different track, this isn't in the style of previous works so don't promote it in the old way, treat me as a newcomer. Just entering the domain of interstellar sci-fi, corrections on details are welcome. ]

Based on the popular Vocaloid series, by HoneyWorks, called “Kokuhoku Yokou Renshuu (Confession Rehearsal)“:

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club. However, instead of being honest about her feelings, she makes him be her confession “rehearsal” partner. Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

Time travelling from the majestic era after the Recuperation of Reiki, he became Kimura Kazuki, a 16-year-old high school student in Japan, one year before the Reiki Recuperation.

Tentatively, he set out to hone himself to the bone, burning candles at both ends to stockpile resources in preparation for the imminent Recuperation of Reiki. His goal was to be many steps ahead of all humanity when the time comes.

However, it seemed like fate had decided to play a cruel trick on him.

One year later, the Recuperation of Reiki… did not happen as expected.
