The Ultimate Guide to the Most Extraordinary Animal Companions in Isekai Anime

In the anime industry, there are various unique settings and narratives, but one constant element is the presence of reliable animal companions. Whether they are simple pets or powerful familiars, these animals add a relatable aspect to anime. Some even become unofficial mascots for their respective shows, demonstrating their popularity among anime enthusiasts.

The same can be said for isekai anime, where these escapist fantasies often feature animal companions assisting the heroes on their journeys. As most isekai series are set in fantasy worlds, these companions are far from ordinary animals. Infused with mysticism and magic, these creatures loosely fall into the "animal" category. Nevertheless, they serve as invaluable companions throughout these extraordinary isekai adventures.

7 Proud Wolf (My Isekai Life)

Despite being named ‘Proud Wolf,’ this animal companion does not live up to its ambitious name. However, after being tamed, it becomes a loyal familiar to Yuji and serves as a reliable companion and ally in battle.

Despite resembling a wolf, Proud Wolf is a fearful fighter and runs away when confronted by someone stronger. The fact that Yuji's slimes were able to overpower Proud Wolf clearly shows its weak nature. Nevertheless, Proud Wolf has found its place among Yuji's crew and remains a faithful companion until the end.

6 Fel (Campfire Cooking in Another World with My Absurd Skill)

Inspired by Norse Mythology, Fel, a Fenrir (a wolf monster), becomes Mukohda's first familiar in Campfire Cooking. Remaining true to the mythos, Fel's immense wolf-like appearance exudes an air of mysticism. However, his personality contrasts greatly with his awe-inspiring looks. Fel is characterized by his prideful and insatiable nature.

While he may not be the most extraordinary animal companion, Fel fulfills his duties admirably as he keeps Mukohda company and ensures that other creatures and monsters respect his master. As long as Mukohda can prepare mouthwatering meals, Fel has no qualms about serving as a familiar to a mere human from another realm.

5 Ranga (That Time I Got Reincarnated as a Slime)

Ranga, despite not fitting the image of a typical animal companion, wholeheartedly embraces his role. Even though his master is a slime creature, Ranga remains fiercely loyal to Rimuru and willingly assists him whenever needed.

Despite being a Tempest Star Wolf, Ranga possesses qualities reminiscent of a canine, including unwavering loyalty, protectiveness, and a carefree demeanor ingrained in his nature. However, to those who are not his master, Ranga presents himself as a formidable creature, ready to defend with his sharp claws against anyone who dares to challenge him.

4 Ponta (Skeleton Knight in Another World)

This adorable little cottontail fox captivates viewers with her playful behavior and endearing personality. However, Ponta's cuteness is occasionally overshadowed by her insatiable appetite, as she frequently begs her owner for treats and indulgences.

Despite her small size and appearance, Ponta is remarkably resourceful and intelligent, often assisting Arc during challenging times. Spirit animals are known for their ability to detect malevolence and evil, but Ponta sometimes disregards her natural caution in pursuit of delectable treats.

3 Night (I Got a Cheat Skill in Another World and Became Unrivaled in the Real World, Too)

Despite his cute appearance, Night is actually a powerful creature with a Level above 500. His impressive stats and battle skills make him the ideal companion for Yuya as they explore the new world.

Night is not only resourceful and versatile, but also capable of sensing impending danger, leveling up alongside Yuya, and defeating monsters in combat. However, being a great companion requires more than just resourcefulness. Loyalty and support are essential qualities that Night possesses, making him one of the top animal companions available to Yuya.

2 Kirara (Inuyasha)

Despite being a Nekomata demon, Kirara takes on the appearance of an adorable two-tailed cat. However, this charming exterior hides her true nature as a fearsome sabertooth demon, always ready to fight alongside her allies. Though Kirara may seem like just a companion to the main characters, her role is actually quite significant in the series.

In her sabertooth form, Kirara possesses the ability to fly, serving as Sango's primary means of transportation for covering long distances. Additionally, Kirara makes a special appearance in Inuyasha's sequel, Yashahime, solidifying her status as a beloved recurring animal companion in the franchise.

1 Puck (Re:Zero)

Puck surpasses the role of a mere animal companion in Emilia's life. Throughout the series, this feline has consistently gone above and beyond for her. Acting as a parental figure and even sacrificing himself by entering stasis to preserve her life, Puck's steadfast loyalty shines through.

Beyond his endearing personality, Puck's appearance adds to his charm. Standing at a mere few centimeters in height, he can easily fit into the palm of anyone's hand. However, it is his trademark droopy ear and mischievous behavior that endears him to all. Undoubtedly, Puck effortlessly balances the somber tone of Re:Zero with his playful antics.
