Only had time to read the first two episodes for now, but I'll give some feedback based on that.
So far, it seems pretty good! Tournament style series are my jam, the introduction gives good context but is short and to the point, and I think even as early as the first episode including a showcase fight to give new readers a taste of what's to come was a good choice! The art is also generally pretty good. The characters and backgrounds are both well-drawn. The only comments that I have are nit-picky things, or personal preferences so take them as you will.
First of all, you might consider removing the first "episode" that is just the cover page. I don't think too many people would actually be put off by that alone, but it takes up unnecessary space in the episode count, especially since you include the cover page at the start of each episode anyways.
Next this is a personal thing, but some folks might agree- I'm not a huge fan of screen tone texture in webcomics tbh. They have a definite place in print comics as they're a way to keep printing costs down by allowing a book to be printed in pure black & white rather than gray scale. In web formats, however, they can sometimes muddy up a drawing and make everything a little harder to look at. Especially in cases where the dots are rather large like this:
It adds a lot of texture to an otherwise un-textured surface that I don't find particularly appealing. In stark contrast, some of these panels that are done in pure black and white are super crisp and look very clean. Particularly panels featuring the samurai guy in the first fight:
Beautiful. It's a stylistic choice so don't feel compelled to change it just because of me, but I think that full fill grayscale would read better in areas where it's needed.
My last comment is just that the design of the main girl here will likely be rather polarizing lol. With a design like a virgin killer sweatshirt variant, a short skirt that allows for a panty shot upon her first introduction, and... I'm not even sure what cup size breasts, you're losing out on universal appeal right from the get go. Some people will definitely be there specifically for that, but similarly a large portion of potential audience may be repelled by it as well
For example I don't mind a bit of fan service in works that I read but I had an immediate "oh jeez" reaction when she was introduced sleeping in the ship, in a pin-up style pose to boot lol. To throw an alternative example out, I think the cowgirl from the first fight has a really cute and sexy design as well, but if she were the main character even it might not elicit such a strong reaction because it's toned back a little bit. Again, though, just my opinion and food for thought- I don't expect you to go redesigning your main character or anything xD
Best of luck moving forward
