What's with all the thous and thees toward your great sempai!? Bit rich coming from someone born in the Shouwa-era! 'Gozaru'-speech, indicating someone who speaks in an antiquated manner like a stereotypical ninja or samurai. Shouwa era: Dec 25, 1916 – Jan 7, 1989. Mikasa was built in the Meiji era, the same era Rurouni Kenshin is set in.

Nay... I do not go as far as actually using those words... Takao doesn't use -gozaru as a copula though.
