Seirei Gensouki: Spirit Chronicles

After fleeing the Beltrum Kingdom's capital with his former teacher Celia Claire and his bonded spirit Aishia, Rio finds himself facing another crisis. People from his past life in Japan have been unexpectedly scattered across this new world. He hurries to their aid, rescuing a small group and offering them shelter. Among them is Miharu Ayase, a childhood friend from his previous life. But they aren't the only ones brought here. With both old friends and new allies at his side, Rio begins searching for the other summoned individuals while looking for a way to return them to Japan. Yet even as he helps others, his true objective remains unchanged: to avenge his mother’s death.
