Ao no Miburo —Shinsengumi Hen—

"What people see as beautiful varies from person to person." Nio is a young boy who has a desire to change the world and continues to stand up again and again, even though he grieves over his cruel fate. Having lost their major pillar, Serizawa, the Miburoshi-gumi changes its name to the "Shinsengumi" and makes a fresh start.
