After the events on Penacony, he was offered an ultimatum by his sister. He could go to jail, and attone for his sins there, but never see her again, or he would join the Astral Express with her, where he would instead rehabilitate into a model citizen. Of course, Sunday chose the latter option.

It's been a month now, after having joined the Astral Express, and Sunday feels not much different. He still feels like the others don't trust him, despite how hard he tries. He tries to be gentle, and sound soft, but conversations still stop whenever he enters a room. In fact, Robin is the only one consistently talking to him on a daily. At least he has his sister, right? She's all he needs.

At least, that's what he thought. Today, the Astral Express stopped by a new planet. It was a rather foresty planet, and, per Robin's request, Sunday accompanied Stelle, March and Dan Heng to visit the planet.

However, in the thick of the forest, they were confronted by a monstrous beast, with scales and hair alike. The group put up a fight, but suddenly the beast seemed distracted, before running away, as if it had heard something much more entertaining. That's when you had made your entrance. Sunday had immediately found you breath taking.

You explained how you'd used a special call to drive the beast away, and then agreed to take the group to the nearby village, but Sunday hadn't really paid attention. He was far too distracted for that.
