15 [Similar Anime] Like A Lull in the Sea

In the sense of atmospheric mood--sweet adolescence romance between childhood friends! The sentimental feels that you'll get from watching the two are very alike where sometimes you just want to burst out in sheer joy for the characters or weep for them. Both have a drab of supernatural or out of the world charm that makes the love polygons more than any ordinary childhood crush.

Both NagiAsu and AnoHana are some of the best works that the oddly-specific "teens in a love polygon with a fantasy or supernatural element" genre has to offer (seriously, there are so many of these, it's ridiculous.)

Nagi no Asukara and Shinsekai Yori shares a variety of similarities ranging from their strict societies to discoveries of their worlds. Similarly, they both consists of a small cast of colorful characters each with their own personalities. However, their relationships with others and each other seems to often clash involving contrasting ideologies.

Both from Shinsekai Yori and Nagi no Asukara take place in world slightly different than the one we're in. At first glance they don't seem that similar, one's more light and happy while the other's are a little more tense and thrilling, but when you look into it the plots of the 2 have a very similar feel and flow to them that I haven't seen in many anime.

Nagi no Asukara & Glasslip both gives a feel of drama between friends who have been together for a long time. These story starts with the involvement of another person that created a domino effect aka one thing leading to another. They also share similar genres and art, plotted in a small town.

Ano Natsu and Nagi no Asukara shares a similar theme of youth during. The characters from both series aren't fully adults yet so they learn to grow up and learn the world around them.

Kokoro Connect and Nagi no Asukara both contain supernatural/fantasy elements in a setting where there is also romance, drama, and relationships.

Love is basically a central plot theme in this story, as well as conflicts in the character's atmosphere. While the story deals around on love, other conflicts such as a home town sea, or amnesia memories, became an obstacle of the main character's motivation and must deal the situation as they advance through. It is all about the drama, cries, memories, and losing something important, hang in their for 24+ episodes.

I do not really know how both similar actually, but I just feel that both anime has that 'feels' to it.

A slice of life anime with a glaring supernatural element that governs the story.
This includes a character driven plot where all of the main cast has a fleshed out character development (save a minor few), a solid romance storyline, breath taking animation, memorable music, and copious cliff hangers and plot twists that will give you "the feels".

Both are stories about relationships and human connections with fantasy elements. Themes of change and time are strongly present in both. Both have very strong emotional impacts. Excellent music throughout, though Nagi no Asukara is certainly the strongest for this.

A bright, ocean-themed show which follows a group of close friends who are drawn to the same interests. However, due to their different personalities, conflicts often appear. Transitions into a serious, exciting story halfway through where only the friends are capable of saving the town from a mysterious being living in the sea they so love. Throughout the show, adults and parents are major supporting characters.

Clannad AND Clannad after story is what I recommend because they both have great art, sound, characters and sadness put together. Clannad's story is basically all arcs but it's still a great anime as well as Nagi no Asukara. I have to admit, you need a lot of patience for Clannad/After story because watching both is about 48 episodes but if you only watch one season then you probably would get bored. Clannad after story is sort of better than clannad but I would recommend Clannad first because well, it's the first season. These animes are both romance, drama and sort of fantasy so I highly recommend Clannad!

There have been many shows that features a group of friends having love interest with each other and/or one of the character in the group will fall in-love with someone foreign to them and Sakurasou no Pet na Kanojo and Nagi no Asukara are example of the said theme. While Sakurasou does not feature supernatural creatures like Nagi no Asukara but features weird people, they both have the same feeling and the most important part of both, the characters' development that improves the show more.

Toradora! and Nagi no Asukara both involve a group of friends who attend school together. Toradora! is based in a slice of life, school environment. The setting of Nagi no Asukara is similar, but there is a supernatural twist to it. In both anime, the leading male character often takes care of a dependent female character. The two anime spark drama through the conflicting love interests of the characters. They both have great artwork--the artwork for Toradora! is great for being almost 5 years old and the artwork for Nagi no Asukara is superb, standing among the best of the best. They both progress at a good pace and are very enjoyable to watch.

Both of them are light hearted series that become more serious towards the end. They're about people who live in the sea interacting with people who live on land and facing a supernatural disaster.

P.A. Works present two series with a similar atmosphere and touch of fantasy by the names of RDG: Red Data Girl and Nagi no Asukara.
