As a child picked up by Shen Huang, Shen Huan grew up alongside Shen Wei and the others.
Life in Luoyang was wonderful, until Shen Wei entered his "rebellious phase."
Shen Huan was "forced" to board that pirate ship with Shen Wei.
And so began a pirate life of matching wits with Shen Wei, loving and fighting one another.
During all this, Shen Huan's true identity was revealed.
Then Shen Wei teamed up with Shen Le to start a sibling battle, all in order to defeat their bald old man.
Faced with one challenge after another, how will Shen Wei and Shen Huan handle it all?
(Actually, there aren't really any challenges, because nothing stands a chance against the absolute strength of the Yato. (Just kidding.) Mainly because this story is a wacky comedy like the original Gintama, with the main plot woven in, and it has a happy ending, so there won't be any insurmountable obstacles or problems that can't be solved.)
