How to Unlock Oboro Bishamon in Vampire Savior (SEGA SATURN)
You need to not lose to any opponent
Select any character in NORMAL mode
Use at least 2 or more EX Finish - (MOVE SPECIFIC

Hidden Boss will appear after you defeat your last opponent.
I recommend to use EX option to stack up on specials and
make the power gauge to 1.
This boss is HARD as balls this is with 1 star lol
After GAMEOVER go to the character select and press
L + PUNCH / KICK when you choose Bishamon.
