Itoshi Brothers — BULLIES

Sae Itoshi – The Cold Playmaker

Background & Aspirations

Sae Itoshi is celebrated as one of Japan’s greatest football prodigies and has already made a name for himself on the international stage, training in Europe with elite clubs such as Real Madrid’s youth system. Disillusioned by domestic Japanese football, Sae openly looks down on it—he’s been quoted saying he’d rather die than play for the national team. Yet, after witnessing the Blue Lock project and the potential in Japanese strikers, his perspective softens ever so slightly.

Personality & Style

Sae is unflinchingly arrogant, blunt, and ambitious. His singular aim is to become the best midfielder in the world. He notoriously doubts the talent of Japanese players, regards his peers with disdain, and has little patience for what he sees as mediocrity. Despite this, he is a consummate professional—compassionless, yet respectful to true talent when he sees it.

Technically, Sae excels in ball control, vision, and precision passing—his dribbling is subtle yet devastatingly effective. He plays with control over the tempo of the match and can shift seamlessly between team-driven playmaking and solo breakthroughs.

Motivation & Internal Conflict

Sae’s move from striker to midfielder wasn’t just a stylistic shift—it was born from self-realization. He recognized that although he might lack the raw scoring instinct, his strategic thinking and creativity made him better suited to orchestrate the game. His return to Japan was driven by curiosity about the Blue Lock project and the possibility of seeing players who matched international standards.

While he appears harsh toward his brother, some theories suggest that Sae’s cruelty may actually be a twisted form of tough love—pushing Rin to forge his own identity and strength. Ultimately, Sae is a tragic figure—once a hopeful prodigy, now burdened by the realization that he may never be the best striker himself, channeling that ambition into becoming the best midfielder instead.

Rin Itoshi – The Obsessive Striker

Origins & Drive

Rin began playing football under Sae’s influence—idolizing his brother and striving to walk in his footsteps. When Sae left for Europe, Rin didn’t falter—he intensified his training, even self-studying English to understand commentary and keep pace with the world’s top play.

Style & Philosophy

Rin is a genius striker whose playstyle is calculated, ruthless, and bordering on puppeteering. He analyzes the field several moves ahead, controlling the game like a battle commander, coining philosophies like “Soccer is a battle to the death”. His football is not about camaraderie—it’s about dominance and intent.

Inner Turmoil & Identity Crisis

Sae’s return shattered Rin’s world. Not only had Sae abandoned their shared dream of being strikers together, but he declared he’d become a midfielder instead—crushing Rin’s idolization in a single blow. The betrayal pushed Rin into darkness. He vowed to surpass Sae, to honor the dream they once shared even more aggressively.

This schism also symbolizes Rin’s transformation. He abandoned camaraderie for obsession, training relentlessly and embracing isolation. He even began to shape his identity around being not just “Sae’s brother,” but a fierce egoist in his own right.

The Struggle for Self

Despite his cold exterior, some view Rin not as a villain, but as a child betrayed, pushed beyond his limits—someone whose entire sense of self came from his bond with his brother, only to have it ripped away. In the U-20 match, many note that Sae’s pressure indirectly helped Rin rediscover his own style: raw, instinctive, and pure rather than derivative.

Their Dynamic – Rivalry Carved from Love and Ambition • Shared Dream → Shattered: They once shared a dream: to be the best strikers in the world. Sae’s decision to pivot and his cold dismissal crushed that dream from Rin’s perspective. • Tough Love or Cruelty?: Sae’s harshness might be a twisted way of forcing Rin to stand on his own, rather than living in Sae’s shadow. • Two Paths, Same Obsession: Both are obsessed—but Sae channels his into perfection in midfield, while Rin focuses on claiming the striker throne for himself.
