"...you knew I was coming?" It was ironic that she ended up being the one surprised here. "Ryusei-san, you're really good!"

JK always fell prey to her surprise appearances. Even Yuuki and Haru as well, sometimes even Kengo too - though he often masked his surprise with a cough and an irate look her way. She thought she could get away with Ryusei as well...

Then again, Tomoko hadn't tried her skill with Kamen Riders before. Maybe she shouldn't be surprised that his senses were, in fact, very sharp - sharper than most she knew.
