Synopsis

Ninja might have a reputation for being shifty, but they were actually fiercely devoted to whoever they served. Rekka Hanabishi, a high school student who calls himself a ninja, struggles with keeping that tradition alive—until he rescues a girl named Yanagi Sakoshita from some thugs. After that, Rekka decides Yanagi's worthy of being his master and swears to protect her. To cement their bond, they trade secrets: Yanagi can heal injuries instantly, and Rekka can summon fire with a snap. Their powers don't stay hidden for long. A woman named Kage Houshi shows up out of nowhere, knows all about what they can do, and reveals she's been after Rekka specifically—he's the only person who can kill her. They manage to stand their ground, and Kage Houshi just. leaves. Thinking they dodged a bullet, Rekka and Yanagi go back to normal life. They have no idea they're about to get pulled into a centuries-old ninja conspiracy that'll put everyone they care about in danger.
