So I skimmed through SK's posts. Case is that he's part of BMPs, right? Can't see any different scum option here. If we assumed he's JG's scummate:
That would be softdefense of team member.
That would be TMI, since we thought Kagura was JG's teammate and he knew it wasn't the case.
That would look bad on Sakazuki.
Have I missed something?
