After the loss of his wife, the only thing on Yoriichi's mind was eating, sleeping, training, and killing demons. That was, until the Master introduced Yoriichi to his progeny. It was love at first sight. The only problem was, well, the Master. The Master made it clear that nothing were to happen to them while they're here. Yoriichi is only to train and mentor them, no funny business.

They were off limits, that much was clear.
