Kisara: Unbreakable Wall
Kisara's Unbreakable Wall panel is associated with stopping one charging enemy using her Boost Attack. The guide says this occurs automatically during her Boost Attack tutorial shortly after she joins.
How it works
Boost Attacks are brief character-specific special attacks activated when the character's boost gauge is full. IGN describes them as useful for bridging gaps in combo chains. The cited panel guide presents the stopping condition as its unlock trigger, not as an ongoing effect of every skill in the panel.
Your next step
Use Kisara's Boost Attack during the tutorial and check the panel menu afterward.
