在仙魔共存之世，桃山大王小桃花因与宿敌打架不慎跌下山头化为原型一束桃枝，却被一个名为长留的俊俏僧人捡回庙中悉心照料。桃花渐渐对长留产生感情，但长留似乎对桃花有所隐瞒，还牵扯到一段不为人知的过去。
Not only is Marinette Ladybug, the superheroine that protects Paris from the attack of villains, but she’s also now the guardian of the Miraculous. This means that not only does she need to keep her identity hidden, but also the existence of these turbulent, magical creatures, the Kwamis! Marinette has a lot of pressure, not to mention her school and love life! Now she has less time and opportunities to tell Adrien her feelings... Marinette now has to redouble efforts to protect her secrets and Ladybug will have to become stronger to face an indomitable adversary: Shadow Moth, who can now fuse the Butterfly and Peacock Miraculous! Thankfully, Ladybug can count on Cat Noir and their new superhero allies!
