Yuki Nonaka is one of the most important characters from The Testament of the New Sister Devil. Unlike most girls that we've seen in the series, Yuki is actually the childhood friend of Basara Tojo. She initially had zero idea of how strong her childhood crush would become.

Like Basara, Yuki is a member of the hero clan tasked with protecting the human world from deadly threats. She's one of the most reliable support characters in the series, consistently dedicated to Basara and willing to do anything for him.

Yuki's unwavering loyalty, strength, and dedication to her mission make her one of the most beloved characters in the series. Her blend of a strong figure, captivating personality, and supportive vibes makes her an unforgettable anime waifu.

Personality and Appearance

Yuki Nonaka is a calm and well-mannered individual. She's frequently viewed as the rationalist within her group, staying cool even if threatened. She is not only a sexy beauty but has the brains to make complex situations simple.

Although stoic by nature, Yuki has feelings, all of which are for our beloved Basara. She displays loyalty to him in her life and choices and frequently places his needs before hers. Yuki is a trustworthy and dedicated ally but an important asset to the human world.

From a visual perspective, Yuki is very stunning and has more of a sexy petite figure. She has gorgeous blue hair that is quite different from any other character in the series. Her yellow eyes are beautiful, and the school uniform of Hijirigasaka Academy, which she usually uses, enhances her attractiveness.

However, her personality isn't all that calm. Once she learned about Basara's relationship with Mio, she made it seem like Mio was just a hindrance to peace. But after a lot of convincing, both become close to each other.

As for her battle suit, it's tightly wrapped around her slim figure, making her look sexier. It looks like a suit made for a female horse. This battlesuit consists of a navy blue leotard, a gorgeous black collar, and a cute white skirt.

Powers and Abilities

Yuki is a lifetime member of the Hero Clan, so it makes sense that she's strong! She can defeat most humans and a wide range of demons. In the series, she is a B+ Rank, which isn't Basara's level, but it's good enough to make her badass.

At some point in the series, her powers skyrocketed because of the Master-Servant Contract. Her contract with Basara increased her strength a lot. She even fought one of the strongest demons known as Zest.

Here are some of her abilities.

• Magic Barrier: By using the tip of Sakuya, she can create a magic barrier and protect herself from attacks.
• Superhuman Strength: Yuki can easily slice through her opponents using a powerful weapon called Sakuya. She even releases a wind blade by swinging her sword.
• Exceptional Healing: Yuki can use magical healing abilities to recover from damage that is out of a regular human's reach.
