Why March Comes in Like a Lion is One of the Most Emotional Slice-of-Life Anime Ever

When most people think of slice-of-life anime, they imagine charming, lighthearted stories about everyday life—high school dramas, quirky friendships, or perhaps coming-of-age tales filled with humor and romance.

But March Comes in Like a Lion flips this narrative on its head by delivering a deeply emotional, heart-wrenching story that deals with themes of mental health, loneliness, and the search for personal growth.

This anime doesn’t just tug at your heartstrings; it feels like a punch to the gut in the most beautiful way.

But what sets March Comes in Like a Lion apart from other slice-of-life anime? Why does it leave such a lasting impact on its viewers?

Let’s break down what makes this show one of the most emotionally charged anime of the genre.

The Complex Protagonist: Rei Kiriyama’s Struggle with Depression and Loneliness

At the heart of March Comes in Like a Lion is Rei Kiriyama, a 17-year-old professional Shogi player who is both an incredible talent and deeply troubled by his past.

Rei’s struggle with depression, loneliness, and the weight of his responsibilities is what gives the show its emotional depth. He’s a boy who has experienced tremendous trauma—losing his family at a young age and becoming a Shogi prodigy at the cost of his own happiness.

Rei doesn’t just pass through life; he’s haunted by the pain of his past, and his journey is about learning to cope with it. What makes Rei so compelling is how his emotional struggles are presented with such honesty.

We watch him navigate life in a world that seems overwhelming and cold, and we can’t help but relate to the feelings of isolation and inadequacy that so many of us experience in our own lives.

His growth isn’t instantaneous or easy—it’s painful and slow, but ultimately, it’s incredibly satisfying.

The Power of Found Family: The Kawamoto Sisters

One of the most beautiful aspects of Rei’s story is his relationship with the Kawamoto sisters: Akari, Hinata, and Momo. They aren’t just side characters—they become Rei’s emotional anchor, offering him the comfort and warmth that he so desperately needs.

Through their interactions, March Comes in Like a Lion explores the concept of found family in a way that feels genuine and tender.

Akari, the eldest sister, is especially important to Rei’s development. She becomes a motherly figure in his life, showing him compassion and understanding when he needs it the most. Her influence helps Rei begin to trust others, despite his deep-seated fears of abandonment.

The Kawamoto sisters provide a safe space for Rei to heal, and they teach him that family isn’t always about blood—it’s about love and support when you need it most.

How the Series Handles Mental Health with Sensitivity

Mental health is a central theme in March Comes in Like a Lion, and the series handles it with remarkable sensitivity. Rei’s depression isn’t something that’s glossed over or romanticized—it’s shown as a very real, very painful part of his life.

The series doesn’t shy away from showing how depression can affect a person’s everyday existence, from Rei’s inability to connect with others to his overwhelming sense of worthlessness.

The anime also takes care to show that healing isn’t linear—Rei has moments of progress, but there are setbacks too. This realistic portrayal of mental health struggles helps normalize these experiences for viewers and allows for a deeper connection with Rei.

The show serves as a powerful reminder that it’s okay to not be okay and that reaching out for help, as Rei does with the Kawamoto sisters, is one of the bravest things a person can do.

The Themes of Growth and Self-Discovery

At its core, March Comes in Like a Lion is about growth—not just Rei’s, but the growth of those around him as well. Rei’s transformation from a withdrawn, isolated boy to someone who begins to open up and accept help is deeply emotional.

What makes this so impactful is how the anime highlights that personal growth takes time—and it’s never easy.

As Rei confronts his feelings of inadequacy, guilt, and depression, he learns to find balance in his life. He begins to embrace the connections he forms with others, and slowly but surely, he learns to live for himself, not just for his profession or past.

His journey is one of self-discovery, and it’s a powerful reminder that growth comes with setbacks, but it’s worth it in the end.

The Gorgeous Art Style and Music: Enhancing the Emotional Experience

The visual style of March Comes in Like a Lion is as much a part of its emotional impact as the story itself. The watercolor-inspired animation gives the series a soft, almost dreamlike quality, which contrasts beautifully with the often heavy themes of the story.

The art style reflects Rei’s internal state, with softer, almost ethereal imagery contrasting the dark weight of his emotions.

The music also plays a critical role in conveying the emotional depth of the anime. The first OP, “Answer”, sets the tone for Rei’s journey—poignant, hopeful, and reflective.

The combination of music and visuals creates a uniquely immersive experience that heightens the emotional impact of each moment.

A Slice-of-Life Show That Doesn’t Shy Away from Real-World Problems

One of the reasons March Comes in Like a Lion resonates so deeply is that it doesn’t present an idealized version of life—it shows the struggles, the hardships, and the growth that come with it.

While many slice-of-life anime focus on lighter, everyday events, March Comes in Like a Lion dives into the gritty, raw parts of life that many other shows avoid.

By confronting difficult issues like mental health, trauma, and personal failure, it offers a refreshing departure from the typical “feel-good” formula found in many slice-of-life anime.

The result is a more authentic, deeply emotional story that feels more real and relatable to viewers.

My Final Thoughts

March Comes in Like a Lion isn’t just another slice-of-life anime. It’s a story of healing, personal growth, and the power of human connection.

In tackling complex issues like depression, family trauma, and loneliness, it stands out as one of the most emotional anime of its genre.

Rei Kiriyama’s journey is one of struggle, but also of hope, proving that even in the darkest times, there is always room for growth and connection.
