Literally it's one one of the best anime I have ever watched actually I will 10000000000% to it, not just 5 stars it is full of all emotions I have launched,got angry, shocked and even cryed at a curtain scenes
In the 1st season they try to run away from the orphanage and in the 2nd season they try to run away to the humans world
It really is an interesting anime ,just listen to me and see that anime I bet you will definitely love it 💞
