Raphael reminds us that backups are important.
Diablo of course have no problem handling 3 of the Seven Days Clergy. I think the manga handled this scene better, kudos to Kawakami-sensei or whoever came up with the idea of Diable crumpling space like paper (not so obvious in the anime), worked very well with the manga medium. (It's chapter 96 if you want to check it out.)
Oh, the great Luminous reveal. I am so confused that Rimuru only just figured it out this episode, but I might have been spoiled at the time I read / watched Walpurgis.
Rimuru wonders why Luminous is able to use holy magic. This will come up again.
Hinata's backstory. It seems she's quite powerful even as she just arrived to this world, gained 2 unique skills. I checked the end credits and there's no credit for the "Voice of the World"...... do we know why it has the same voice as Raphael?
Rimuru proves himself as an adult in the past life, admitting he was staring at Hinata's beautiful body when confronted instead of having childish reactions.
The great Luminous reveal part 2, this time from Veldora to the holy knights. He really gives Luminous reasons to punish him, which she does with that special skill / technique that works well for spiritual beings like Veldora.
Too bad the anime put the after action party in the ED rather than spending more time with them. It could also have got into more details of why the Seven Days Clergy did what they did. I still think the pacing is off with this season.
