There's a number of things.
My first encounter with the series was when I stumbled upon a short review of the game that was featured in Nintendo Power back in 2009 (the Wii remake, as you can guess). The review was positive getting a green "Nintendo Power Recommends" (the ratings went from Green>Yellow>Red). What struck me as odd is when it said that the game had an incredibly sad ending. It only showed the box art and some screenshots of the first level, so I was thinking "What are they talking about, this game looks cute and fun, not sad". I watched a walk through of the first level (still on Wii, I had no idea there were any other games). My brother and I thought it looked good, but we never got the game in the end.
Fast forward to only a few months ago. I was browsing /v/, and stumbled upon a Klonoa thread. I was like, "Oh yeah! This is that game for the Wii that I wanted." Thankfully I went into a thread that somehow managed to stay relatively "clean". The question the OP asked was "How would you describe Klonoa's personality?" Lots of people said "clinically depressed", which reminded me of the sad ending that Nintendo power mentioned years ago. Sadly enough someone vaguely spoiled the ending of the first game, only saying that "It's sad because in his canon, Klonoa doesn't exist". Although people started arguing about how true that was, it got me more interested. I left that thread, and started doing research on the games, where I learned that there was actually quite a few games, and not just the Wii one.
I made two of the biggest mistakes possible, I looked up a video of the ending first, and searched for the English VO as well. After seeing why people hated the English VA (that, and I couldn't find a full play though of the game in English anyways), I watched a walkthough of the Wii game in the original voice acting (and eventually watched the PS1 version of the ending for comparison). I now understood why it was so sad. I got the game on a PS1 emulator for Android (sorry), and learned why people liked the gameplay too. I watched a walk through of the other games (never owned a PS2, and didn't want to pirate the GBA games).
After I read the ShiftyLook comic (a month after they stopped updating), I was finally caught up with the story. Eventually I found another Klonoa thread on /v/, and saw the kind of crap that people posted, and learned from others that this was the kind of crap that you would normally find in a "/v/ Klonoa thread". I wanted to do something about that, I wanted these threads to actually be good for a change. I got my hands on a few translated chapters from the manga, and waited for the next thread. Surprisingly the next thread appeared a day later, and I was able to post it before the thread started going downhill (as shown
here).
I found out about this community from the Klonoa Wiki, and saw that people were working on archiving the manga. I thought I might as well contribute, and joined using the pseudonym NebulaVista (You never know what kind of people are on 4chan). After finding a copy of the manga 100% translated, I shared it here to help darai in his efforts.
I've been trying to keep Klonoa threads from going south on /v/, and hanging out here ever since. (Well, as far as the Klonoa community goes. I do lots of other things too.)
