Rekka then meets Yanagi Sakoshita, a lovely girl with the power to cure any wound or harm. Their meeting puts in motion a series of events that end in a terrible revelation. Rekka is the last survivor of a renowned ninja clan that was exterminated years ago. Even more amazing than being a true ninja, he also wields the power to control fire. What does this mean for Rekka? Who are these strange people after him and Yanagi? Find out in Rekka no Honoo!
