Aria The Animation, Kamichu! Recommendations
Both are slice of life, and slow paced. Also, they both make atleast me smile. I guess you could say that they also give a similar "Aura".
Colorful visuals, pleasant music, lovable characters, and interesting premises of fantasy and nostalgia. Both are relaxing slice of life stories about cute girls with unusual occupations. If you enjoyed either of these, watching the other series is a must.
A peaceful slice of life, very organic and relaxing. The art is also similar in the sense of round and shiny character designs.
Both fall into the "relaxing" slice of life genre rather than comedy. Watching either show just puts a smile on your face and helps you forget all your cares.
