Ah, he didn't trouble Izuminokami that much did he--

The sensation of Izuminokami running his nails lightly against his scalp causes him to give a high, sharp yelp. He straightens abruptly as he shouts, then just as quickly folds in half, his head to his knees and his hands over his face.

He groans unintelligibly into his knees, "This is why I can't ask Touken Danshi to do my hair..." But although Izuminokami probably (hopefully) didn't catch that, Tonbokiri's neck is about as red as his hair, which should give a good hint to how he feels about this.
