is one of the major characters of the Magical Girl Lyrical Nanoha series, but not Triangle Heart. He is voiced by Kaori Mizuhashi. A mage and archaeologist at the age of nine, he comes from Mid-childa in search of the Jewel Seeds and becomes Nanoha's partner. He is also a shapeshifter, turning into a ferret, and is thus often mistaken for Nanoha's familiar and serves the same function. He was the original owner of Raising Heart. He is also referred to as Yuuno Scraia, Yuno, and Euno, the latter being a reference to Eunos cars, as the names of the Wolkenritter were in a possible reference to Magic Knight Rayearth.

The [http://www.nanoha.com/character/yuuno.html official website] romanizes his name as Yuuno Scrya.

Before the start of the series, Yūno lived in Mid-childa, a magical world, as an archaeologist. He had no parents, so was raised by his entire tribe, the Scrya, from which he took his surname. He also obtained or created the intelligent device Raising Heart around this time, but his talents lay as a support mage, and so his attack abilities were low and he never made the device into a weapon.

Yūno first appears running from a gigantic monster in the woods and attempting to seal the Jewel Seed inside it with Raising Heart. He fails, letting the monster get away, and collapses wounded on the ground. Yūno uses his remaining power to call out to the nearest magic user and turns into a ferret. His call was heard in Nanoha Takamachi's dream, and later that day, she found the ferret in the woods and took him to the veterinary hospital. He quickly recovered, taking a liking to Nanoha and recognizing her as a possessor of the magical aptitude, a rarity on Earth. Later that night, he calls out to Nanoha again and she leaves the house and finds the Yūno-ferret cornered by the same monster. He entrusts her with his weapon, Raising Heart, and seeing her raw power when she activated it, deduces that she can create magical armour and turn Raising Heart into a weapon of her design. She does so and begins her journey to seal away Jewel Seeds.

Yuno Scrya has not been a contender in any CBUB matches.
