Jester is a main character in the anime and manga series Children of the Whales—also known as Kujira no Kora wa Sajou ni Utau—and plays a pivotal role throughout the story. As one of the key figures on the ruling council of the Mud Whale, a mysterious floating island home to individuals who wield a psychic force called thymia, Jester stands out not just for his position but for his sharp mind and strategic thinking. He’s someone who always seems to be several steps ahead, especially when navigating the complex dynamics among his fellow council members. And honestly, you can’t help but notice how often Jester uses his cunning and manipulation skills to maintain balance—even if his methods sometimes walk the line between questionable and justified.

Now, while Jester might come across as a bit shady at times, it’s important to understand that his actions are deeply rooted in care and loyalty toward his people. He genuinely believes that the isolation of the Mud Whale is essential for their survival. In his eyes, contact with the outside world isn’t just risky—it could be catastrophic. That kind of protective mindset doesn’t come from nowhere. There’s more beneath the surface with Jester, especially when you consider his complicated past. Though much of it remains a mystery, there are hints that he knows far more about the world beyond the island than he lets on. And let’s not forget: this knowledge likely stems from a traumatic experience he went through during his youth, something that clearly shaped his worldview and his determination to shield others from suffering the same fate.

One of the most touching aspects of Jester’s character is his relationship with Chakuro, the protagonist. Over time, Jester becomes a mentor figure—a trusted confidante who offers guidance, support, and even the occasional reality check. It’s clear that Jester sees something special in Chakuro, and their bond adds emotional depth to the narrative. Through moments of humor, tension, and quiet sincerity, Jester proves himself to be not just a political player, but a deeply human presence within the story.

When we look at Jester through the lens of personality typology, things get even more interesting. For instance, many fans and analysts believe Jester aligns closely with the ENFP personality type—Extraverted, Intuitive, Feeling, Perceiving. Now, what does that mean exactly? Well, ENFPs are often described as enthusiastic, imaginative, and highly attuned to emotions—both their own and those of others. And wouldn’t you know it, that fits Jester pretty well. He’s incredibly sociable, radiates energy, and has this almost instinctive ability to read people. Whether he’s diffusing tension with a joke or offering heartfelt advice, Jester connects with others on an emotional level, which is a classic ENFP trait.

That said, he’s not without his flaws. Jester can be impulsive, making decisions based more on gut feelings than cold logic. Sometimes, he jumps from one idea to the next, easily excited by new possibilities but less focused on following through. Still, his optimism and zest for life are contagious. Even in dark moments, Jester brings a spark that lifts the mood and reminds others to keep moving forward.

Switching gears a bit, some also speculate that Jester might fit the Enneagram Type 7—the Enthusiast, or sometimes called The Epicure. This type thrives on adventure, novelty, and stimulation, often avoiding discomfort by seeking joy and distraction. And honestly, that tracks. Jester loves exploring different corners of the Mud Whale, trying new things, and keeping the atmosphere light with his humor. But here’s the thing: that lightheartedness might also serve as a coping mechanism. When serious issues arise, Jester often deflects with jokes or playful banter, which could suggest he’s using humor to avoid confronting painful emotions—something commonly seen in Type 7s.

Of course, it’s worth noting that personality typing isn’t an exact science. While Jester shows strong signs of being an ENFP and possibly a Type 7, he’s a layered character who likely draws from multiple types. Human beings—and fictional ones like Jester—are rarely boxed into a single category. So while these frameworks offer useful insights, they don’t capture everything.

In the end, Jester remains one of the most compelling characters in Children of the Whales. Whether you’re drawn to his intelligence, his emotional depth, or his unique way of balancing duty with compassion, there’s no denying his impact on the story. And throughout it all, Jester continues to stand out—not just as a strategist or a council member, but as someone who truly cares. So yeah, when you think about Children of the Whales, it’s hard not to think about Jester. Because whether he’s cracking a joke, guiding Chakuro, or quietly carrying the weight of the past, Jester is always present—always watching, always protecting.
