Locked in her room in the Otoan Palace, Luna Shinomiya was struggling to endure an immense pain. She her was lying on her back, and her body was naked and slick with sweat.
"Aagh!"
Luna grunted in pain. Her toes curled and she gripped her sheets hard while arching her back. There was a glowing magical crest carved in her skin on her midsection, right below her breasts. It was a symbol representing one's status as a summoner--a contract link to the Spirit World.
After completing her training, her mother had finally granted her wish to help Luna contract her spirit summon. Lana's training had been a brutal ordeal. She had believed that Luna's beliefs were all wrong. She was the heir of the strongest barrier user, yet she had nearly committed the grave sin of letting her barriers crumble.
