One day, Hiko was training Kenshin how to refrain from being numbed by extremely cold temperatures in battles...
When a ship came sailing straight towards them...
Kenshin notices, then Hiko too...
Kenshin: Shishou...a black ship...
Hiko: It's headed right towards us.
Kenshin: *eyes glimmers* It's breathing fire, Shishou...
Hiko: I have eyes, baka deshi.
Kenshin: A black water ryuu?
Kenshin: It's heading for this iceberg.
Hiko: Remember what I taught you?
Kenshin: Hai! Hiten Mitsurugi Ryuu...Ryu-Sho-AHHHHH!!!! (slips on the ice and promptly plops into the icy waters below)
Hiko: Sasuga watashi no baka deshi desu...[You really live up to your reputation as my 'stupid disciple'...]
Hiko: *Oh no, the ship is going to get my baka deshi!* Hiten Mitsurugi Ryuu, Ryuu Kan Sen!
A cracking sound is plainly heard.
Kenshin: Shishou! Help! I'm freezing. No... wait, I'm drowning too!
Kenshin: Shishou... I think you just sunk the ship.
Hiko: One more word and you're going down with it.
Hiko: Watch me hack the ship down, then you come out of the waters with a Ryu Sho Sen, get it?
Kenshin: Hai! Go Shishou go! You do a Ryuu-Tsui-Sen and I'll follow up with a Ryuu-Sho-Sen, soudesuka?
Hiko: *stares* Hiten Mitsurugi Ryuu... Ryuu Tsui Sen!
Kenshin: Hiten Mitsurugi Ryuu... Ryuu-Sho-Sen!
Titanic splits into two.
And starts sinking...
