That explains that, I suppose. We already saw Rin's medical dungeon room where she's nursing the comatose Jin back at the end of Chapter 41, and now we finally have the context.

I actually wonder if this "rich jackass" thing is just a ploy. Last chapter we had Shijouin's father talking about how he was going to make sure that the MC can "survive his taunting and jeers of my interview" because he wants to make sure MC isn't a spineless coward, and then the very next moment we've got a long-time family friend of the Shijouin's suddenly getting in Niihara's face, taunting him and challenging him to a duel over the finals. The rich guy is cartoonishly dramatic and self-centered, but notice that's something that both Niihara (last chapter) and Genji (this chapter) seem confused by. They hadn't heard anything about him being a narcissistic jackass when people were gossiping about him (which seems like a pretty prominent character flaw for people to have left out of their rumors).

I wonder if this whole thing isn't just the father calling in a favor from a family friend to try and figure out if the MC hanging around his daughter is a wimp or not.

Jin's ability was (is?) telekinesis. Rin used Jin's telekinesis against Nana back when they got into a fight in one of the earlier chapters.

Yeah I'm pretty sure it was a joke-translation. The sudden surfer vocabs would have been one thing, but Nakajima and the new journalist guy rhyming like they're in a Dr Seuss story was a little too on the nose.

Finally got around to reading the rest of this. Geezus.

Page 3 bugs me, and not just because of the open ending (I share the scanlator's opinion about that). What exactly is Makabe even remembering there? Aki never called him Piggy/Pig's Foot. That was like the whole big reveal of the original story, and how he managed to figure out Yoshino's treachery. Whatever he's remembering there didn't happen. So: what exactly are we looking at in that panel? Is it Makabe 'remembering' one of his rage-induced hallucinations? Or did the author just forget a major plot point (my money's actually on this one)?

I agree with the general feeling that we're getting towards the endgame here, so for fun and curiosity's sake I went through the previous chapters again to see if we could gauge the winner. Here's the lists of "dedicated chapters" (i.e., chapters where it's almost exclusively that girl interacting with Daisuke, or where there are clear romantic overtones focused on that character's pairing with Daisuke specifically):

Kotone (19 chapters): 15 32 41 46 70 98 120 129 169 190 215 252 254 276 296 304 311 323 351
Chiaki (27 chapters): 6 13 29 39 43 58 71 86 116 119 133 143 161 170 181 204 206 216 217 241 256 260 285 299 314 339 350
Suzu (21 chapters): 11 23 30 33 40 52 77 80 104 137 146 163 198 229 248 253 268 291 316 326 353
Asahi (4 chapters): 141 183 201 239
Nonoka (6 chapters): 56 76 138 156 266 336
Tanaka (16 chapters): 95 121 131 142 148 164 185 203 208 228 257 264 275 297 319 349
Reiko (26 chapters): 14 16 34 42 57 74 94 111 123 127 140 158 168 180 184 191 205 213 226 234 245 273 295 307 325 354

Chiaki's in the lead, which probably isn't surprising given the popularity poll from a few months back. I was surprised to see that Reiko had so many chapters where it's just her and Daisuke together, though. I always felt like she was a bit of a gag character, but in terms of one-on-one interactions she's always had most of the other girls beat throughout the course of the manga. Kotone and Suzu also had fewer romantic rendezvous with Daisuke than I thought they did. Assuming Reiko doesn't swoop in at the last second, I know who my money's on for the Daisukebowl.
