This one puts a kid's face on the Shinsengumi and then makes you watch what that costs. Nio is an orphan sweeping up in Mibu in 1863, and the show never lets you forget he's a child standing next to men who kill for a living. That's the trick: the townspeople spit the word "Miburo" like a curse, Serizawa Kamo proves them right every time he's drunk, and Kondou Isami's warmth only makes the gap between the ideal and the blade sharper. Okita Souji is the real dagger here, all sunny grin until the smile stops reaching his eyes, and the series knows exactly how long to hold on that shift. History has already decided how this ends for every man in a pale blue haori, which is why Nio's stubborn belief that the world can be made better lands like a bruise. Twenty-four episodes of a boy learning what justice actually smells like.

In 1863, as the shogunate nears its end, Japan's capital is torn by violence between wandering ronin and government samurai. Nio Chirinu, an orphan who waits tables at his adoptive grandmother's restaurant, still holds on to a strong sense of justice and a hope of making the world better. His life changes when Hijikata Toshizo and Okita Souji, founding members of a despised ronin band called the Miburo, use Nio and his sister Iroha as bait to catch child abductors. Afterward, Hijikata invites him to join the group and protect the people of Kyoto. Nio trains hard to reach his comrades' level with the sword, tries to win over Tarou Tanaka and Hajime Saitou, the Miburo members his own age, and works to hold on to his conscience amid shifting loyalties. The historical drama is adapted from Yasuda Tsuyoshi's manga.
