The song: No clue. Ding Dong the Witch is Dead? 

Substantive Point: As you probably remember Osamu is supposed to be meeting with the Ichigawa before the raid. If you do want to skip that still you could hold off for Oblivion and I to briefly discuss what would happen in that meeting and inform you of the results so you could just mention the outcome in your post. Certainly that would be quicker than doing the whole meeting but I don't know how Oblivion feels about that.
