Absolutely! It's very easy to assume the blood is a stylistic choice, but it's still hilarious that they had a very obvious 'wait, that's not right' detail out in plain sight from the very beginning, and the twist at the end is 'yep, that's not right'.

I'm glad to know I'm not alone in failing to click with Yuma/Kurumi! I did wonder at first whether I was just being contrary.

Riona: I ship Yuma with everyone!
Rain Code: Great! Please ship him with this character.
Riona: No.
