Wow, 2 more sub plots that didn't make it in the anime
One of those was the story behind Hayato's purchase of a ¥100,000 animal caricature that also explains Apachai's origin story to Ryozanpaku (or as the manga now calls it "Ryozampaku", just like the Niishira Alliance is now the "Shimpaku Rengou"). I'll probably let it slide since Hayato ends up erasing Ken'ichi's memory to prevent him from snitching. But the other one is when his dad visits the dojo with a gun! Admittedly I kinda heard about this in the subreddit, but I thought it was later in the story. Turns out, the anime didn't feel like adding it in, and it was wild! Seeing his dad try to shoot everyone and I think he reloaded with one hand because his other one was holding his barely conscious son, which Shigure thought was impossible. But what got me was when he punched Sakaki in the face who just tanked it.
