Forgive me while I set up this place!! My main tumblr is FuuMiku, I made this blog to gush about my fishing obscure interests like tsuritama and River King: Mystic Valley! Other non-fishing things like the manga Nankoku Tom Sawyer by UME fits in too, nothing like summer days spent outside by the sea
River King Mystic Valley additional content & resources
River King Mystic Valley is a DS game about fishing released in 2007 in Japan as 川のぬし釣り こもれびの谷せせらぎの詩, in 2008 in North America as River King: Mystic Valley, and in 2009 in Europe as Harvest Fishing. This ds game is one of my longtime special interests and I’ve done extensive research into it and merch. I figured I might as well share for the other few unlikely fans.
Sites
https://fogu.com/rk5/ : Incredible fansite which gives in depth information on every facet of the game lore and gameplay mechanics in english. It even has forums for the game that saw activity in 2025.
https://www.marv.jp/special/game/ds/kawanushi/ : Official website, all in japanese. There are newsletters about the game’s production and release from the time, for example a newsletter on release day from the staff, don’t be scared of the very retro interface this is a treasure trove. There are very short exclusive comics not found anywhere else. Graphics not found anywhere else as well.
Books
There is an official strategy book with lore and production info, but mostly game mechanics, called 川のぬし釣りこもれびの谷せせらぎの詩完全攻略ガイド. It's 143 pages and you can read its release announcement here. It's still rather easy to find being sold online.
Fami2comic (ファミ2コミック) ran a River King Mystic Valley manga by Igusa Matsuyama from july 2007 to september 2007 in their magazine issues. You can read its announcement here. To read it yourself, I recommend: https://archive.org/details/fami2comic200707/078-079.jpg 79 to 94 for chapter one, from the july issue. https://archive.org/details/fami2comic200708/118-119.jpg 119 to 134 for chapter two, from the august issue.
https://archive.org/details/fami2comic200709/128-129.jpg 129 to 136 for chapter three, from the september issue.
And https://randomhoohaas.flyingomelette.com/ai/scans/fami2comic.html#riverking for overall fami2comic info
Its first two issues were however released in its own small book. This book is labeled as book no. 01, but as far as I know there was never another one, since there was only one more chapter afterward. I couldn't find it stored anywhere online, but I do have a physical copy I might get the bravery to scan one day, it seems to have a few exclusive things not included in the other Fami2comic issues. It's 35 pages, and very hard to find sold anywhere.

It’s honestly one of my absolutely favourite shows and it’s all-around a wonderful story about finding passion, overcoming boundaries and building strong and meaningful friendships, also it has aliens so it’s pretty much perfect.
The main character, Yuki, is a character I hold very dear to my heart.
He’s a kid who deals with anxiety which this anime depicts FANTASTICALLY.
Everything Yuki feels and does, his drowning feeling, the inner monologue, the way his flashbacks at the end of the day are depicted, is on point with how anxiety feels to me. Being someone who dealt with and occasionally still deals with crippling social anxiety, this anime spoke to me on a very personal level and I absolutely adore the growth Yuki goes through in the short 12 episodes.
Not only is anxiety depicted very well, but the interpersonal relationships between the four main characters develop EXTREMELY beautifully and naturally. Their friendships and how they behave within them makes a lot of sense with their different personalities. They are extroverts and introverts, they come from different backgrounds and with different motives and manage to create very genuine bonds with each other. I keep noticing new aspects of their relationships every time I re-watch this show.
I don’t want to say too much about the plot because I don’t want to spoil things, but it’s unusual, full of surprises, full of emotions, full of excellent character development, and it combines science fiction with fishing, of all things.
ALSO, IF YOU LIKE BRIGHT FRESH COLOURS, THIS SHOW IS ABSOLUTELY FOR YOU!!!
The colours in this show are some of the most comforting and pleasant palettes I’ve ever seen in an anime! It’s very bright and colourful and perfectly saturated to retain a general feel-good touch throughout the entire run.
I HONESTLY CAN’T RECOMMEND THIS ANIME ENOUGH. IT’S ONE OF MY ABSOLUTE FAVOURITES AND IT MAKES ME SO SO SO HAPPY.
“That summer I changed.
I finally found something I was really interested in.
I always had friends by my side.
And I even surprised myself
by how loudly
I learned to laugh.“
