Joukamachi no Dandelion

Both have a group of students with super powers, but with different histories and goals 

Both feature various characters with special powers, and the animation of both series is very bright and colorful. I personally felt both series had very likable and unique characters, and I really enjoyed the soundtrack to both.  

Both are lighthearted SoL shows with comedy and a little bit of character development thrown in. Joukamachi has a few slightly darker points, but both generally try to keep an upbeat and happy atmosphere. There are romantic subplots in both of these shows, but the romance is much more prevalent in Working. Joukamachi tends to delve into themes such as family and friends, putting romance to the side save for a couple characters. Working has no supernatural elements, while Joukamachi has a very central supernatural core with the royal family's powers. Generally, if you liked one of these shows, you'll find something very similar between them. 

They both are about royals and the struggles one can have involving them and their rules. They both also has a similar feeling when you watch it. 

Both Main Character(s) are in a high standing position and they are popular among their locals. Both are slice of life anime with the main character(s) having some sort of superpower/magical powers. 

Both about towns with supernatural abilities and mostly about the characters I guess.  

While Dandelion doesn't have the same high-level production values as Hinamatsuri, it is also basically a slice-of-life comedy about children with super powers, so I think people that enjoy one are likely to enjoy the other. 

They have superpowers but different on all of them..... But still there in highschool or since birth adapted powers by a comet or a father :) 

Though there's nothing particularly similar about these anime, they both give off this sense of fun, lightheartedness that is just a joy to watch. These shows both have a large ensemble of characters who are all a pleasure to watch. Finally, the setting of these anime are both very light, but do have a goal to be accomplished at the end (Earning enough visitors for Amagi Brilliant Park, and seeing who the next king/queen will be in Castle Town) I enjoyed both, so I recommend both xD 

Both are anime that are split into at least two different stories per episode. 

Both is about royal family. 

both have family relationships as a main focus - ookami does it through a mother taking care of two growing kids, dandelion does it through daily activities and interactions between the siblings. albeit, ookami is more drama focused whereas dandelion is more comedy-oriented, but both are have plotlines that focus on the family and interactions between family members (instead of focusing on one character that does things who happens to have a family) 

Both have comedy, good characters and are relaxing and fun to watch.
