Gintama: Season 1, Episode 48

1 - 48: The More You're Alike, the More You Fight / Whatever You Play, Play to Win

A group of assassins want to take Hijikata out. The problem: none of them really didn't expect what would happen when he encountered Gintoki who, with Shinpachi and Kagura encounters an old man and was "forced" to play games with him; meanwhile, Sa-chan's master passed away and she went to attend his funeral.
