On page 9, Kaoruko saying she's worried about "Haruka and the others" is pointed out as a tell that she's in love with Haruka. Then, on page 21, Utena chides Imitatio for getting "Sayo-san and the others" involved. Thinking emoji
In fairness, the context for that is slightly different because she's talking about the other magical girl team being targeted. She would expect her villain team to get targeted. But yes, that does mean Sayo is her favorite from Tres Magia. But this isn't cucking Leopolt or anything. Besides, we've already established OT3 is endgame. Provided they don't try to make the harem even bigger, that is, with new characters.
Nonsense, it just needs to be done by the team that did Valkyrie Drive
Maybe I should rephrase to say I don't see anyone doing it justice in the modern scene. You gotta remember Valkyrie Drive was seven years ago now. Takagi has since left Maverlous, which has lead to the near destruction of the Senran Kagura brand sadly, and Hiraku Kaneko's last project was Kandagawa Jet Girls (which was another joint project with Takagi before he left) which was much less lewd and sadly much less gay than Valkyrie Drive. I'm still salty how the first episode pretended the premise was a strip jetski racing anime only to back off from it on the next episode. I haven't heard any news about him since, which is a shame as his credits for lewd anime are among the best.
