I read in Wikipeada that in Masked Form, Thru The tubes on his
armor, "Profromace Enhanceing Drugs" Are Suppled to Sasword.
Tetsrugi, The Next Barry Bonds? What do you think?
In the series the tubes were just for show since Tsurugi didn't actually use whatever special liquid it was. If anything he was more like Doc Ock using those tubes to bind Tendou. But no sign of him becoming all muscle-bound.
