I really like when this manga go from "funny romcom with fanservice" to "Battle manga with op main character".
I'm... not a fan of what's happening storywise (always hated the "let's fight for a girl" trope, they're not freaking trophies damnit), but I like the fact that Nanase know that Tetsu just won't accept him with a mere challenge, but he want to be accepted by him anyway because he know how her brother is important for Kasumi.
Anyway, thanks for the chapter!
And about the next one: take your time. I think it's better to wait a bit more and get the full experience instead of trying to cut it in little part and take the risk to lessen the impact.
(also, you reminded me with your last comment that Stradew is going to be updated again soon. I need to play again.
