Spoiler for spoilers:

Apparantly Kumokawa know about Touma's memory loss. Her 'love letter' was there to smoke out the agent working against her but is also keeping a eye on Touma. Kumokawa's ability is some sort of hypnosis.

And why would the agent be keen on a 'love letter' sent from her to Kamijou Touma ?
