Avrora

From Inga no Kusari wiki

Avrora is Demetri Arsov's fullbring.

Like his Quincy father influenced his attacks, his mother is the source of this Fullbring. A mother provides a seemingly all powerful defense. His mother loved the Aurora Borealis, and when in the need of defense, this is his first reaction.

Fullbring Ability

By using the opposite effect of Polyarnaya Zvezda, he forces his own reiatsu into the environment. The entrance of his own reishi into the air creates a moment of aurora like effect. This shield last only for a few seconds, but can block out both spirit and physical attacks. (Attack Tier - Avrora tier = damage)

Strengths

Near-instant: As long as Demetri has a tiny bit of reiatsu, he can quickly create this shield.

Weaknesses

Instance effect: While he still has limited control over his own reiatsu, Demetri can usually only hold this shield for a second or two.
