Neco-Arc is a beloved character from the anime Carnival Phantasm, which is a comedic spin-off of the visual novel series Fate/stay night and Tsukihime, both created by TYPE-MOON. Neco-Arc is essentially a playful parody of Saber, one of the most iconic characters from the Fate series, but with a fun and feline twist. As a cat-like warrior, she brings a unique charm to the franchise with her eccentric personality, lack of self-awareness, and an undeniable love for fish.

Originally, Neco-Arc made her debut as a humorous side character in the Japanese role-playing game Melty Blood, which came after the massive success of the Fate series. Though she started off as a silly addition, her popularity quickly soared, leading to appearances in other TYPE-MOON titles such as Fate/stay night: Unlimited Blade Works and Fate/Extra. Her distinctive feline traits, including her large cat ears and fluffy tail, make her one of the most easily recognizable characters in the franchise.

Within Carnival Phantasm, Neco-Arc is a recurring character who thrives on creating chaos and mischief among her fellow warriors. She often dives headfirst into absurd challenges or joins in on wild antics with other characters from both the Fate and Tsukihime universes. While her unpredictable behavior and occasional bursts of violence can stir up confusion, fans adore her for it, making her a standout presence in the series.

All in all, Neco-Arc adds a lighthearted and entertaining dynamic to Carnival Phantasm. Her quirky design and comedic personality ensure that she leaves a lasting impression on fans of both Fate and Tsukihime. Though she may not possess the same level of seriousness or combat prowess as Saber, Neco-Arc brings a sense of fun and joy that never fails to bring a smile to viewers’ faces.

Looking at Neco-Arc from a personality perspective, he could be classified as an ESFP type—someone who is outgoing, sensation-seeking, emotionally expressive, and adaptable. His extroverted nature shines through in his interactions, as he often seeks out new experiences and enjoys being the center of attention. His deep connection to sensory pleasures, especially his obsession with tuna, further supports his preference for sensing.

Neco-Arc’s emotional depth is also quite apparent. He reacts strongly to situations and is sensitive to the feelings of those around him, which aligns with a feeling-based personality. Additionally, his spontaneous and carefree attitude, paired with a tendency to avoid rigid plans, points to a perceiving trait. He thrives in the moment and embraces whatever comes his way without hesitation.

Putting it all together, Neco-Arc’s vibrant ESFP personality really comes through in his energetic and cheerful behavior, his sensory-driven actions, his emotional responses, and his flexible, go-with-the-flow approach to life.

From an Enneagram standpoint, Neco-Arc fits the profile of a Type 3 with a Two wing (3w2). This means he’s not only driven by a desire to succeed and be admired, but he also has a natural charm and a desire to connect with others. He’s the kind of character who loves being in the spotlight and can easily win people over with his playful antics. When he feels overlooked, it can frustrate him, as he often goes out of his way to stand out.

Despite his love for attention, Neco-Arc also shows a caring side. He may be focused on his own achievements, but he’s not entirely self-centered—he’s willing to lend a paw to others when needed. This blend of ambition and warmth makes him a surprisingly well-rounded character beneath all the comedy.
