The Island Closest to Heaven (天国に一番近い島, Tengoku ni Ichiban Chikai Shima) is the third episode of the 2007 anime series Seto no Hanayome.


Nagasumi's father's work calls that his company's project changed deadline date to a shorter date which cuts their family visit short and must return home to Saitama the following day. Nagasumi and Sun get to spend a whole day alone on a deserted island to get to know each other and Nagasumi hesitates to tell Sun about their sudden parting. However, this proves to be a trap meant to eliminate Nagasumi. It is revealed that the notorious assassin of the Seto Group as well as a longtime friend of Sun, deemed Maki "the Conch", is after his life. Nagasumi then tells that he must leave the following day due to what transpired but Sun too was meaning to explain to Nagasumi she is going to live with his family as part of the mermaid's marriage code. This further upsets Maki as well as her father. As they depart, Maki then slips in Nagasumi's backpack to watch over her which concerns Nagasumi even further.



  • Desserted Island
  • Coral reef: Located at 45 meters below the blue ocean, it was a recommendation asked by Maki to Sun. Unnaware of it's exact depth, Nagasumi accepted to visit the Coral reef. Upon arrival, we saw how happy and relaxed Sun was, how Maki's face revealed an evil plot to eliminate (AND DROWN) Nagasumi, and Nagasumi...Well...Humans cannot withstand a water pressure of 45 meters below the ocean level. I seriously hope Nagasumi finds a way to be a Waterbreather.


  • The episode's title is a reference to the notebook, The Island Closest to Heaven.
  • Sun needs to learn more about humans, since this episode showed her that humans cannot withstand water pressure as she(Which makes me ask myself how can she?) and proably she don't know yet that he cannot breathe underwater since he would have been drowned already


Gozaburō (To Nagasumi): (Sticking outside the bullet train's window) The only thing I can do....The only thing I can do now...The only thing I can do for my girl is watch over her!
