Synopsis
After trading Tokyo for a quiet seaside town, Futaba Ooki doesn't know a single person. She's the kind of girl who hides behind her phone camera, cataloguing everything at a distance instead of actually living in it. Then she meets Hikari Kohinata, a local girl who's completely obsessed with scuba diving and has the energy of a golden retriever. Hikari latches onto Futaba, nicknames her 'Teko,' and basically drags her into the school's Diving Club run by their laid-back homeroom teacher. What follows across 12 episodes is Futaba slowly opening up: learning to breathe underwater, learning to breathe above it too. The scuba diving stuff is genuinely detailed and kind of fascinating if you've ever been curious about it, and J.C.Staff nails the coastal scenery and underwater sequences with this lush, warm animation style. The soundtrack by Gontiti is all acoustic guitar and gentle melodies, the kind of thing you'd put on while napping in a hammock. This is pure iyashikei: healing anime. Nothing bad happens. Nobody dies. You just watch two girls become friends and discover something beautiful together. If you liked Aria the Animation or Tamayura, this is cut from the same cloth. Even fans of K-On! who want something with a similar friendship dynamic but a more contemplative pace will find a lot to love here. It's the anime equivalent of a deep, slow breath.

My favorite anime
It's a beautiful episode that showcases the wonders of diving, and we also see the climax of Futaba's development, all unfolding at a smooth and visually stunning pace, allowing you to fully appreciate the scenery. It's truly a beautiful ending, and the soundtrack is incredible as well.
This is another light and relaxing chapter, nothing to do with a dramatic or intense plot; it's more like eating a piece of cake.
This was a more relaxed episode with a less dramatic plot; it feels lighthearted, but it's good to see the characters behaving like what they are: just teenage boys who want to have fun and hang out.
I genuinely believe this is one of the most profound episodes of this story because we can see Futaba's nostalgic side. Sad but beautifull at the same time
This chapter is lighter; I like how it tells different stories and allows us to get to know the characters' dynamics more deeply. The twins add a very dynamic touch to this story; it's quite relaxing.
A very calm but entertaining chapter. This type of narrative helps the characters interact more with each other and connect better, creating a good dynamic of trust, especially when it's not all about diving.
I feel this chapter has a slightly faster pace, which isn't bad, but I'm glad the plot doesn't stagnate and tries to move forward, involving all the characters in a fun but also very mature way.
I love how the personalities of the new characters contrast with those of the established protagonists; it's quite fun and adds a more comedic touch, in my opinion.
This episode is quite interesting and it's incredible how the characters interact and help each other. Tekko's conflict is understandable, but the way it unfolds makes you empathize with her.
This chapter was slower than usual, however, the characters' reactions to the conflicts seemed pretty cute in their own way. very charming
It iss a tender interaction between the characters, and how they gradually get to know each other and relate to one another; it's one of those slow-paced anime that are enjoyed for their simplicity. over all this episode
It's a good start, something fresh and organic as you see how the main characters interact; Hikari is adorable. By the way, the characters' uniforms are beautiful.
A chill episode to end the series. This episode also showed the relationship between the main characters has gradually grown closer since they first met. I'm excited to watch Season 2, as this anime always delivers a calm and relaxing vibe that I really enjoy.
Another cute episode with the calm vibes alongside the main characters.
This episode is full of cute and wholesome moments between the main characters, and it also shows the development of their friendship.
This episode is one of those episodes that makes you realize the realities of life, while also reminding you to enjoy it to the fullest, no matter what.
This episode is full of sibling banter and interactions between them, which adds another wholesome atmosphere to the anime series.
This is another calming episode. The atmosphere of the scenes make you feel calm after a busy day.
This episode once again taught me more about diving. It also contained some cute moments between the main characters.
