To Quarkboy, maybe it's just me, but I really hope you just keep the "Rinshan Kaihou" untranslated. After all, it's a special yaku and the special ability of the main character. You're not gonna translate literally another yaku in the next episode, right?
Looks like Gonzo is using all the flashbacks that can be used. It's a valid technique, knowing how the source material is left. Quite surprising to see the end they use today but overall, this is the crux and this is the match where things really heat up.
On the story, I'm really impressed with Kajiki's calculated thinking. She's really someone who reacts accordingly to the situation and responds in the best manner. Her decision to go for "Steal Kong" is really quite something. We'll see more.
Nice touch with battle outfits. I guessed this works as well. Now, everyone is a gladiator of sorts.
New OP was meh. ED was slightly better.
To those interested, in Tenhou, Rinshan Kaihou comprised on average 0.3% of all yakus in all games. That's how rare it is. Interestingly, the other
one is also 0.3%. Was it on purpose?
