Thomas knew his decision to go to the Underworld was rash.
He didn't know anything about the Underworld, he didn't even know the way to it. Tiersa and Wyern's tracks couldn't be traced with his Devil power at all. He suspected that Wyern used his power to throw his sister away into the Underworld.
But he couldn't ignore his sister anymore, like in the Lotus House. Tiersa had been through enough there, and she didn't want to go through it again.
Iris quietly grabbed Thomas's hand, trying to strengthen it. She is the same as Thomas. She knows absolutely nothing about the Underworld. Her knowledge is zero. Morgan seems to be the same, the Werewolf is only desperate.
In contrast to Yuxie's relaxed face, the other race leader's face was deathly pale, the same as Helios's, who was sitting next to Thomas.
