Before you step through that portal, you might want to check yourself for ticks. There's a good chance a few might have hid theselves on you while you were busy gathering scales.

[Touma spoke from personal experience. His earlier attempts at collecting scales had rewarded him with a good handful of brightly colored ticks and slight blood loss. Although he has no idea where her portal connects to, he felt it was important to warn her about the parasites before she accidentally transports them to her room or somewhere else equally as bad inside Keystone Station.]
