Rosty's actual identity in Wistoria: Wand and Sword could be related to Elfaria Albis Serfort

Rosty Naumann remains an enigmatic character in Wistoria: Wand and Sword to date. Although the narrative introduces Rosty as one of the students at the Rigarden Magic Academy and Will Serfort's dormmate, several instances highlight the character's connection to Elfaria Albis Serfort, one of the five Magia Vanders.

Aside from sharing Elfaria's strong emotional attachment for Will Serfort, Rosty's dynamics with the protagonists strongly suggest he could be related to the Ice Maiden. Interestingly, a popular fan theory widely circulated in the fandom suggests Rosty could be an ice clone of Elfaria.

The theory gains credibility from several instances in the manga where Rosty appears as a mirror image of Elfie. Aside from the manga, the anime adaptation and the prequel light novel further hint at Rosty being Elfaria's ice clone.

Exploring why Rosty could be a clone of Elfaria Albis Serfort in Wistoria: Wand and Sword

From the onset, Rosty Naumann appeared as an enigmatic character obsessed with his dormmate, Will Serfort. Fujino Omori even confirmed with a character profile in Wistoria: Wand and Sword manga that Rosty's first love was Will.

Unlike many other characters, who downplayed Will for being magicless, Rosty never judged him. Rather, he always had his back and helped his dungeon expeditions by crafting magic tools.

However, as the narrative progressed, it seemed like Rosty was Elfaria Albis Serfort's clone. According to Wistoria: Wand and Sword manga and the prequel light novel, Elfaria can create multiple living clones of herself and have them operate independently.

Moreover, the light novel states that Elfaria can create a magic necklace to remotely cast magic, something that Rosty has. The novel further highlights that Elfaria learned to craft magic artifices from an expert using her Magia Vander status. Considering Rosty crafts those tools for Will suggests a definite connection between him and Elfie.

It's not overreach for Elfaria Albis Serfort to create a gender-bend clone of herself to watch over Will and ensure his safety, considering she cares deeply for the boy. Additionally, the manga has several instances where the panels cut from Rosty's perspective to Elfaria.

At the same time, Wistoria: Wand and Sword manga shows the ice maiden reacting to what the characters conversed about while Rosty was with Will Serfort. Moreover, according to the manga, Rosty has water magic, which is part of ice magic.

Aside from these hints, the events at the Terminalia Arc in Wistoria: Wand and Sword manga all but confirm Rosty Naumann as Elfaria's clone. When Rosty gets stabbed by a mage killer in the arc, we see a small ice shard falling from his hand. Undoubtedly, this subtle detail strongly drives the theory home.

Lastly, the anime adaptation of Wistoria: Wand and Sword manga makes it more obvious that Rosty is Elfaria Albis Serfort's clone. The anime has yet to reveal Rosty's voice actor. Some fans feel it's Elfaria's voice actor, considering they sound quite similar.

Additionally, when Rosty appears in the anime for the first time, he's heard humming the series' ending theme song, Frozen. Fans should note that the song highlights Elfaria's feelings for Will Serfort. Last but not least, both the opening and the ending theme songs have scenes where Elfaria and Rosty smile the exact way. It's improbable for it to be a coincidence.

Fujino Omori hasn't officially confirmed whether Rosty Naumann is one of the living ice clones of Elfaria Albis Serfort. However, the author has strongly hinted at the possibility through subtle hints in the Wistoria: Wand and Sword series. It remains to be seen whether Fujino Omori-san confirms it in the future.
