So I was thinking it would play out that Ripple would somehow manage to kill SwimSwim, realize she just killed a child, then kill herself out of shame/despair. Turns out she found out it was a kid and still just went stabbity stab stab on her.
I read the LN right after I got done with the anime to see how many deviations they had after learning Calamity Mary didn't die to 2 kunai strikes in the head.
Yeah, in the LN this didn't happen this way, also even in the anime she was not aware Swim Swim was a child when she made the final strike.
In the LN, she threw her Katana at Swim's heart as they were blasted away by the flashbang, so she didn't get to see Swim's real body. In the anime, she was blinded in one eye and the other had blood obscuring her vision.
This show was alright and a good entry in the "Battle Royale" genre. I'm not too bothered by it, but it's pretty funny how the main protagonist didn't do anything of note while it was going on, even when she strengthened her resolve at the climax. Basically only ended up in her wanting to become stronger in the epilogue; wonder if that is something relevant to the future of this series.
Ripple was pretty stupid to throw all she had at Swim Swim like that. She was explicitly told that her weakness was sound/light. She should have just used the flash bang after she saw that her first volley didn't do anything; I thought she was trying to condition her or something, but she was just being stubborn.
From what I read of the translated LNs, the anime did a very bad disservice to the ending of the LN and the fight scenes.
Snow White did more to help kill Fav on the LN than she did on the anime. In the LN, she threw the master device at Fav's feet after hearing his thoughts on magical weapon Ripple was holding. Also, it was due to being able to hear Fav's thoughts, that she was even aware she could destroy the master terminal to kill him as that meant he was there.
All in all, I do feel bad for Swim-Swim despite all the things she did.
