>"She's following a lead. As for Utsuho..."
>Make it a long story, for Youmu's sake. Talk a bit about how things are underground, so that Utsuho's background is decently understood. About how youkai were sealed there, and have since been forgotten about. Then lead into how she looked over Blazing Hell, and how Kanako approached her. Try to keep the assessment of this as neutral as possible, but make it clear that it was more or less entrapment with Kanako dictating out the whole thing, getting Utsuho to agree, and then not really doing enough follow-up or not caring to. Throw in evidence of Orin immediately figuring it out to establish Utsuho losing it was obvious and should have been noticed. Then take about what followed briefly, and how Kanako defeated her, caputured her, and imprisoned her under the mountain. At this point, go into rather lurid (but accurate) descriptions of her conditions, and how Kanako essentially refused to make more than token efforts to treat Utsuho like a sentient being rather than a cog in a machine, and hides knowledge of it as effectively as she can, including to her own priestess.
>"So you see the problem, I hope. It's that Utsuho is fully innocent or undeserving of some kind of punishment, it's that Kanako doing so excessively and without any real authority to do it, and intends to do so until Utsuho either dies of a sick heart or takes her own life in desperation."
