"That's incredibly risky." Senku sighed. "In this world, this mess apparently the trains are governed by a Ministry. Currently, it's believed that we are considered fugitives, as is the Voidtrecker Express, and all signs suggest that if we're caught by the Ministry, nothing good would happen."

He tapped his finger on his hip as thought. "That's not to say we can't try to contact the outside world, but we have to be incredibly careful. The Ministry is apparently, bad news. We haven't sorted out what other factions or options there are yet, and many worlds we've been to are not void active, meaning that they know nothing about the train or the void."

"Usually, about a week." Senku said, after a moment. He accepted the bottle of water, and took a sip. "....thanks. But they've varied, I think. Depends on what happens on the mission."
