Ah, true~ but that's just one of the reasons. Mitsuzane-kun has already proven somewhat resourceful - he may, with some prompting, be able to push the Beat Riders into investigating some other things for us. As much as our troops have been able to penetrate the forest... well. If he could get them to look for other things in there it would be helpful. They're all stronger than anticipated, and they tend to not go in on their own. Even if they do, they possess Lockseeds stronger than the ones we commonly distribute.

They've proven that they are able to survive just fine in the forest, and as long as they don't do anything extremely reckless we can use them to locate points of interest. We can use them as our eyes and ears in there - and he could push them towards exploring those settlements we discovered. This is no time to be hesitant to use any resources we can, as you know. The Beat Riders are organizing themselves into an alliance for the most part. If we don't have someone inside the situation... even with all of my surveillance I can't capture everything~, especially if they don't have the Drivers with them. You already have an informant willing and eager to provide you with whatever you'd like to know about them.

Besides, as you said, the other options involve removing him from the situation completely, which will only make things worse for both of you.
