Rin returned half an hour after Tenebria left.
She arrived on the Blessed Island and was surprised to see Isabella practicing with elemental instruments.
"What are you trying, Bella-sis?" Rin curiously asked. "Is it related to the Harmony concept?"
Isabella had practically created a small orchestra with twelve instruments. Three violins, three cellos, two trumpets, and two drums.
"Yep," Isabella excitedly smiled. "I awakened Harmony Concept and I am creating an offensive skill that utilizes it."
[Harmony—Concept]
_Realm: Alpha.
_Effect: If you can create harmony with any medium(s), the potency of the effect you produce through those mediums is boosted by 50%.
Rin read the concept's effect, and her eyes shone as she immediately realized the potential of this concept.
"Oh yeah, Tenebria visited here," Isabella said and took out the medallion. She proceeded to tell everything she heard from Tenebria and informed Rin.
