Unlock the Demo's Secret Boss

Issen counter on screen

You can unlock the Secret Demo Boss by performing 10 Issen during the demo. You can find the Issen Counter on the bottom left of your screen.

Issen: Press your Attack Button Just Before Being Hit

You can dodge an attack and hit back with a deadly counter, but it requires even more precise timing than a parry or a Reflex Dodge.

Boss Fight General Guide

The game introduces different responses for different attacks. Most of the attacks can be parried or blocked. Others need to be evaded. Performing the correct attack or defense will make the fight easier.

Learn the different attack patterns of the bosses. This includes when the boss dashes, strikes, or grabs you. It is important to know the basic mechanics of the game.
