The stream is in from NicoNico (niii) Live, so everything is in Japanese. 

The tournament has a version that not only has Min MIn and Helix, but several new weapons available. Including a hammer and a cuckoo clock.

Here's the link: http://live2.nicovideo.jp/watch/lv295553400

Edit: Looks like the winner was a Ninjara player. I really wanted to Ribbon girl player to win, but the other guy was just kept setting up oppertunnites to grab and counter. The matches overall were pretty good.

EDIT: This doesn't seem to be from the stream I watched, but it is definitely from the same tournament.

It was uploaded to youtube. Someone added timestamps so I'll just put them here

First fight at 34:20 2nd at 50:30 3rd at 1:30:50 4th at 1:36:00 5th at 1:43:05 6th at 1:52:10 Final at 3:28:40

UPDATE:

Here's a small part of day 2. There is maybe over 16 hours of the tournament, but the part I really wanted to show isn't wasn't recorded.  Which is a shame because the Ninjara vs. Ribbon Girl fight was insane. That being said there are a some pretty close matches in other matches too, like one with Min Min vs. Master Mummy where the Min Min player barely dodges the opponent's rush and does his own, clinching it. Abadongo, a competitive Smash player is also in the tournament and he had some great comebacks with ribbon girl and really understands how to use DNA Man's abilities. (I think the stretching part stems from holding the jump button btw).

There is a ton of matches on youtube now as well so you don't have to sit through these videos. The matches are just not really in any order though.

Just type ARMS Tournament on youtube and set the searches to today.

I'd be suprised if I didn't pop a boner to her when I was young.  I know my first boner (that I can remember) came from April in the original cartoon...  I was like what's happening?  Why is April doing this to me?

lol! Velma Dinkley for me.

I would Dinkley her Jinkies if you know what I mean but alas she belongs to another

I put one video of the tournament in the OP. Unfortunately this isn't the one I was looking for. Its still great granted, but the Ninjara and Ribbon girl players are really good, so its a bit disappointing to not get show that. Only way you can currently see it, from what I understand, is if you have a premium account. So yeah not really worth it. 

Also if you could keep the thread a little on topic rather than start a discussion about cartoons you got boners over or really wanted to get jinkie with...

This game looks great, first fighter game I've been interested in in years.

After looking at more of the matches myself, they showcased several new costumes for the characters

Ninjara:

Master Mummy

Spring Man:

Ribbon Girl: 

i was skeptical about this game at first BUT its looking to be a great fighter

Oh wow, 4 hours, will tag this for later

I wasn't too interested in this game when they first showed it, but the more they show the more I like it. Even if this isn't the next Splatoon in sales, it probably will be in how much I enjoy it

Lol! Sorry, couldn't help myself. Hahahahahahahaha

Yeah, Arms is looking pretty sweet!
