Nanatsu-iro★Drops

The first thing I thought after having completed both Nanoha and Nanatsuiro Drops is "wow, it's like they're practically the same show". Sumomo and Nanoha both have to collect something, with the help of a cute "pet", which can talk. Sumomo and Nanoha both face similar tsundere "antagonists", Prima Asparas and Feito, respectively. The main difference between Nanoha and Nanatsuiro Drops is that the latter focuses much more on the love between Sumomo and Tsuwabuki-kun. There are plenty of other subtle differences to keep you amused, so unless you dislike the genre mahou shoujo, I'm sure if you loved one, you'll at least enjoy the other.  read more 

In both animes is about magical and friendship, but also love. Both are very fanatsy full. But well done. 

Both about girls who suddenly got an item which allows them to use magic, and they both need to collect something. And both anime's has a blonde haired rival who also want to collect those items. 

In both, the main character finds a talking stuffed animal/ animal and takes it home. The main characters also has to collect stardrops/jewel seeds for their "pet." In both, there is someone else competing for collecting those seeds/drops. 

Mahou Shoujo Lyrical Nanoha and Nanatsuiro Drops have a lot in common; a human who transforms into a cute animal encounters a girl, and the main character begins her journey as a magical girl collecting scattered seeds/drops. Soon, a rival appears who is looking to collect the seeds, and the shows get progressively more dramatic. For differences, Nanoha has a lot more action, and Nanatsuiro drops' main focus is romance. While both include magic, Nanoha takes place in more of a sci-fi setting, and Nanatsuiro Drops is more fantasy-like.  

Nanoha really reminds me of Sumomo and vice versa. Most of the show is kind of based around how moe you think the girls are. 

This really reminds me of CCS because Sakura needs to catch card and Sumomo Drops and they bote had a enemy and a animal to help them 

No use to run from it: Nanatsuiro Drops is a worse version of Card Captor Sakura. The ND story is heartwarming and cute? Yes. Is it well developed? Not at all. If you want to watch some romance featuring a magical girl, give Nanatsuiro a shot, but CCS is WAAAAAAAAAY better on all aspects. 

Mahou Shoujo with a cute storyline, brilliant outfits and stunning animation. 

Both characters have to collect something (Sakura - cards, Sumomo - Drops) and they also have a stuffed animal to help them, also they wear pretty outfits. 

Similar storylines. Both main characters are very cute, very caring, and have a little animal "sidekick" that has much information about what is being collected. Both Sakura and Sumomo adapt to the idea of having magical powers and having to search for the magical items in similar ways. In CCS they are collecting Clow Cards, in ND they are collecting Stardrops. ^O^ Sakura and Sumomo kinda look alike too. ^^ 

Both anime's involve a magical girl in search of some object to save a stuffed animal creature. 

Both Kobato and Sumomo collects something in a bottle and both of them have a little stuffed animal with them.  

Both of them are collecting items for a purpose and both have a little character next to them along on their many adventures. 

Talking stuffed animals, bottles filled with magic stuff and happy smiley mood. 

they both transform and in both anime a certain person lost their past memory but remembers it again in the end 

If fantasy and magic are themes of your interest, then both series may interest you. Plus, there's the comedy, drama, and later romance that comes into play. Both anime(s) contains the magical girl theme with the main heroine being the magical girl.  

Both are magical girl romances. Both heroine have pink hair. Shugo Chara is longer, but it is really worth watching. 

it is also a magical girl,comedy,romance anime. 

Both anime are very adorable and carry similar vibes, plus they are both mahou shoujos with shy and upbeat leads. If you like one of them, you will surely like the other 

Both anime series has outstanding animation while posessing scenes for observing (as well as remarking) on constellations. Inaddition, the shows deal with elements of slice of life that are expressed in a light hearted manner. 

Both are Magical Girls & romance anime, but Nanatsuiro Drops's shorter 

Both shows are about magical girls and their cute animal mascot who collect seed/drops 

Both about magical girls, and have both a cute animal in it. 

Both series focus on humans helping someone small find/collect something important. The series also have cute characters and rivals to the main female character.
