Time passed, and even though Leon and Makoto stayed on the range where they could hear the conversations between Seiji and Yuki, they didn't hear anything useful. Makoto was getting impatient; soon, they would leave the areas where they could chase the train without being noticed, and it would be even harder to collect any information.
"We could always fly above the train, but even if we try to camouflage ourselves, we are bound to be found. I don't have enough mana to chase them under the earth either..."
Although Leon was resourceful, he wasn't omnipotent. There was a limit of the things he could do with the magic he knew and with the amount of mana he had.
"We have to change our plans…"Makoto said. "It looks like Seiji is worried that someone is spying him, that's probably why he isn't telling anything useful."
"So, what are we going to do?" Leon asked.
