Any cure is a slow process.
Unlike this anime, for that matter. Rushed towards the last few episodes, which crush every bit of expectations you were slowly accumulating over the progress of an anime with an unusual theme. It's an absolute pity, because for those who enjoy a nice change of pace, this anime was starting good, if not - at the very least - steadily.
Then suddenly, it comes down crashing when every problem is a medical one resolved by the way of godly powers which absolutely undeserve the anime theme. If you've nothing better to do, you can watch this anime but keep in mind you're likely to be disapointed.
