The Interaction panel can be accessed using the red or deep pink icon labelled [交流]
Using the green [交流] icon, you will enter a panel where you combine four different potions to create bronze, silver, gold or special mixtures for your chosen warrior to consume, improving the intimacy level between you and him.
Each character has a preferred color of crystal; using preferred crystals during interaction heeds a higher chance of higher rarity (and more intimate) potion skits.
Preferred Colors[]
* Tentative
Upon consumption of the potion, the intimacy level of the warrior is increased. Once he has reached 100% intimacy, he would have maximized all available stats and is ready for awakening [覚醒].
To awaken a warrior, click on the red [覚醒] button in the middle of the radar chart for his statistics.
You will get to enjoy a fully-voiced scene along with a CG for this part. You can also choose to apply the following settings to the scene.
You may continue to raise the intimacy level of your awakened warrior again for a second time, until he achieves 200% in intimacy levels.
