Summary
It was a heatwave, so what better way than to end a long day of work with a boat trip while the sun sets? All three of them never knew what fate was actually awaiting them, and unknowingly walked into an adventure that would change all of their lives. Underneath the full moon in the crater of a volcano, they never knew that they would be bestowed a blessing; or in hindsight, a curse?
March, Stelle and Dan Heng have to find out how to balance their new lives while keeping their secrets without any clue what happened, nor what exactly changed. How difficult can keeping secrets really be when you're one drop of water away from spilling everything? Will the shared secret between them drive them closer or actually apart?

Summary
" “Uhm. I don’t mean to interrupt but…” Sunday spoke up, “…this book reads Ghost Huntin’, A Survivor’s Guide.”
“What?” Dan Heng turned towards him slowly and glanced at the small book. Sunday nudged it closer towards him so he could read it. He had been right. The small book did read exactly that.
“Ghost what now?!” March exclaimed. “Hey, wait— how is this supposed to be the Simulated Universe?! It sounds nothing like what you told me about!”
Stelle shrugged. “It definitely isn’t.” "OR

Summary
"It wasn’t like March was a star in "remembering" trivial things that would happen during her travels. Most of the times, she would just shrug them off and act as if she hadn’t seen anything, practically forgetting the small details.
She would leave it up to Dan Heng to remember the details, while she kept taking pictures of sights that were aesthetically pleasing and worth remembering for decades. But if something were to come back more than 3 times, even she would notice it eventually and know something was off. But she didn’t know *what* it was.
That was, until she got to Amphoreus."

Summary
- Captivated by the sweet voice of the angel on the stage, the girl looks over at the stage. Gallagher notices this and watches with her. “Beautiful, huh?”
“Yes… Her voice is exquisite… Like an angel,” the girl takes another sip from her drink, before turning to Gallagher, “Who is she, if I might ask?”
“That girl over there on the stage? That’s Robin. She’s a singer from the Family, a Halovian.”
The silver-blonde haired girl’s gaze fell on the stage again as the songbird sang her lyrics. -

Summary
"Do you not put things in alphabetical order?" Sunday asks weakly, watching as March tears open a box and leaves it at her feet on the floor. His wings twitch anxiously. "Wouldn't that make it easier to find?"
"Oh, Sunday," March laughs, reaching out to swat his arm playfully. "Around here, we just remember where things are. There's no need for any complex systems at all."
"It might be a good idea," Himeko muses, pinching her chin thoughtfully as she gazes up at the shelves. "Well… we've already started. Nobody's ever had a problem with it before, anyway."
Sunday bites the inside of his cheek and swallows blood.
After destroying his own life and leaving everything behind to travel with the Astral Express, Sunday finds himself slipping into old habits.
