Like the name of the titular character, this anime is so sweet and cute that you will probably forgive any fault that you see in it.
The best thing in this anime is the characters. The fairies Sugar, Salt and Pepper are so cute, but not in the annoying way. Choro-sama, the elder fairy, will also make you laugh with his silly antics over his obsession with Ginger - a fairy obviously so much younger than him! Basil and Cinammon are also characters who, despite their bratty and rascal ways, will worm their way into your hearts.
And if you watched Card Captor Sakura, you just might be in for a surprise. The artwork is so similar but the Tomoyo-looking character is the frenemy (friend/enemy) of one of the lead characters - Saga (patterned after Sakura). I found this to be very funny - seeing a totally different Tomoyo. My only complaint about the artwork is that the characters probably wore the same outfit all throughout the series, in stark contrast to Card Captor Sakura\'s numerous costume changes.
The story is simple, but still quite complex. It won\'t let you look that hard for questions about your life, but it will make you wonder if you found your own Kirameki - whatever that is.
