Description
Ichimatsu Matsuno is one of the six identical Matsuno sextuplets. His name uses the kanji for "one" (一) instead of the typical "市松" (ichimatsu, meaning "checkered pattern"), reflecting numerical naming conventions; he dislikes misspellings using the checkered pattern kanji. While his exact birth order was initially ambiguous, recent works confirm him as the fourth son.
As a child, he appeared nearly identical to his brothers, usually in matching uniforms. Early depictions showed slight height and facial variations, but later portrayals emphasized shorter, rounder proportions. He presents as the most serious, strong-willed, and comparatively intelligent brother, though still academically challenged, and exhibits practical tendencies, often saving more money. Despite a reserved nature, he joins group mischief and shows occasional kindness, especially towards younger children like Chibita. He possesses greater physical endurance than his brothers, demonstrated when chasing Chibita up a building. His relationships vary: he frequently pairs with Jyushimatsu for schemes or activities, has fewer interactions with Choromatsu and Todomatsu, and rarely associates directly with Osomatsu or Karamatsu.
In the 2015 reboot continuity, he is an adult NEET. His appearance features droopy eyes, slightly ruffled hair, a hunched posture, and two cowlicks. He typically wears purple casual clothing: a hoodie, sweatpants with a white stripe, and sandals. His personality centers on being a "lone wolf" with a strong affinity for cats, preferring their company over people. This stems from deep-seated insecurity and difficulty expressing himself, leading others to perceive him as incapable of friendship. Beneath a defensive, aloof exterior lies emotional fragility, symbolized by a glass heart labeled "fragile."
A significant backstory revealed in the movie shows that during high school (ages 16–18), he adopted a popular, outgoing persona nicknamed "Ichi," masking his true self. This facade collapsed under social pressure, culminating in a traumatic failure contributing to his adult insecurities. In the present timeline, he struggles profoundly with social interactions; encountering his younger self triggers suicidal and violent impulses, and attempts to revive his high school persona result in exhaustion. His adult relationships remain complex: he maintains a close but strained bond with Jyushimatsu, often supporting him despite visible discomfort, while interactions with Choromatsu are marked by intimidation due to the latter's pursuit of normalcy.
