If you cry too easily you should skip this one. A mysterious Orb is cast to earth who is capable of changing into any life form. The story further progresses after it has changes into a human how he manages with his surroundings and the characters finding the true meaning of his life and his purpose. The story is way too depressing and the soundtrack does it job. You should definitely check this anime. Though it has slow pacing first but story gets more intense as it progress.
