Who is Natsuki Seba in Sakamoto Days?

Sakamoto Days introduces complex characters through explosive narratives, but none quite match the brilliance of Natsuki Seba's twisted genius. Born into violence and molded by harsh circumstances, this dark blue-haired inventor emerged from the shadows of Okutabi Lab.

Natsuki Seba is a 20-year-old prodigy who transformed from Sakamoto Days' most dangerous antagonist into an unlikely ally at the JCC. This skilled weapons expert shoulders the responsibility of protecting his younger brother, Mafuyu, while serving as the youngest leader of the Weapon Production Department.

Natsuki has a lean, athletic build that complements his combat abilities. His distinctive features include asymmetrical beauty marks beneath his black eyes - two under his right eye and one under his left. His messy, tousled dark blue hair falls to mid-length, with overgrown bangs that completely cover his forehead.

The character design in Sakamoto Days emphasizes Natsuki's dual nature through his clothing choices. His signature invisibility suit consists of a shiny dark blue jacket with matching pants. When not wearing the suit, he sports a purple T-shirt, showing his more casual side.

Natsuki's personality mediates the complex character writing that makes the series so engaging. He keeps a lackadaisical mood even during critical missions or when reporting to superiors. This casual, almost apathetic conduct masks his true dedication to completing tasks properly.

Despite his nonchalant exterior, Natsuki has strong work ethics and planning capabilities. He dreams of saving enough money to retire comfortably, showing practical long-term thinking.

The driving force behind Natsuki's actions in Sakamoto Days stems from his devotion to his younger brother Mafuyu. He consistently protected Mafuyu from their father's harsh treatment. His deep bond with Mafuyu ultimately drove him to accept the perilous offer to attend the Al-Kamar Orphanage in exchange for his brother’s safety.

Natsuki's genius-level intellect makes him one of the most formidable characters in Sakamoto Days. His prodigious weapon-making abilities emerged during childhood when he crafted his brother's bladed shoes and training gadgets. Even his JCC peers acknowledge his superior craftsmanship, though he's experienced numerous failures.

His combat prowess shouldn't be underestimated either. Natsuki has proven his combat prowess by holding his own against both Shin and Heisuke. He even landed multiple stabs on Shin and executed rapid, precise attacks while invisible.

The invisibility suit represents Natsuki's greatest achievement in Sakamoto Days. This black-colored outfit allows him and anything it covers to become completely invisible.

His use of a liquid nitrogen bomb further highlights his tactical ingenuity in the series. This spherical device releases massive ice blasts that can freeze entire areas, though it requires a two-day reload period. The weapon successfully immobilized Osaragi temporarily.
