In SiNiSistar 2, some unlockables are not obtained simply by clearing the main dungeons. In this short guide, I explain how to unlock the last CG and trigger the hidden boss fight found in the Highway section.
How to Unlock Last CG in SiNiSistar 2
In this guide, I will show you how I unlock the final CG and the boss fight connected to the Highway section in SiNiSistar 2.
Create the Scivias Powder
After progressing far enough in the story, I can craft Scivias Powder through Haanja in the Cathedral.
This is the item needed to access the final boss fight of the game. Once I have the required ingredients, I simply talk to Haanja and craft the Scivias Powder.
Go to the Specific Location
After crafting the Scivias Powder, I need to go to the specific map shown in the Highway section.
Once I arrive there, I use the Scivias Powder in the middle of the marble pillars. After using it in the correct spot, the boss fight will begin.
Félicitations!
If I manage to defeat the boss, I receive a strong weapon and unlock the last CG.
This CG is one of the several CGs that cannot be obtained just by clearing all of the dungeons.
