Shouji Manjoume

万丈目正司, Jagger Princeton

Shouji, Jagger in the English version, is one of Jun's two older brothers. Shouji is at the top of the financial world; while Chousaku is at the top of the political world. They wanted Jun to be the top of the Dueling world, thus given their family a foothold in the three major industries of the world at that point.
