The samurai shows up, head encased in a deep wicker hat to preserve his anonymity.

The samurai looses Jihei and the hood of his cloak. Jihei instantly recognizes the samurai as his brother Magoemon, a flour merchant, nicknamed the Miller.
His full name is Shunsui Sozosuke Kyoraku no Jiro. Kyoraku no Jiro means "second son of the Kyoraku family" whilst Sozosa means "assistant who conceals all" or "assistant who possesses all."

"Under the old dispensation, sexual competition had been relentless and cruel: for every pair of happy lovers there was a dejected onlooker, the one excluded. Love was its own transparent bubble-dome you could see the two inside it, but you couldn't get in there yourself.
That had been the milder form: the single man at the window, drinking himself into oblivion to the mournful strains of the tango. But such things could escalate into violence. Extreme emotions could be lethal. If I can't have you nobody will, and so forth. Death could set in.

Kyorakus known for drinking and his theme song is a fucking TANGO
