Naginyo is a spirit sent by Princess Grace to lookout for Fine and Rein. His most prized possession is his harp (which he calls it a violin) as he often plays it to entertain ladies and generally spread good cheer throughout the land, mirroring the princesses' mission, albeit on a smaller scale. Fine and Rein find his harp playing skills slightly annoying, but his lyrics actually tell the truth of things. He has green hair and green eyes. His outfit has the symbol of each kingdom. He is the object of Camelot's affection later in the series. It is possible that in the past he was romantically interested in Princess Grace.
