It's not much of one?

[Fortunately or unfortunately, Haruka isn't really familiar with that tone, so he is not unsettled by it.

It's probably for the best.]

Kanon-chan offered to protect me, and I'm not about to turn down that offer, and with the weird thing showing back up again... she's here to watch over me, I guess.

[Is there more to it? Yeah. Is Haruka going to spill? He'll try not to.]
