 Bushido Blade

Get Fighter with Gun
Beat slash mode without getting killed once and you can turn into Katze
Get to the bosses
In order to skip all of the normal characters and go straight to the
sub bosses you must: First, cripple your first opponent so that he/she
CAN NOT walk. Then run to the manhole that you would normally jump
down after defeating the last normal opponent. By doing this you should
be able to skip through about 3 or 4 fights.

Note: Rumor has it that if you do the above and beat all the bosses
without continuing, you get to see your character's secret ending!!
