We start with learning that Kindaichi survived the bombing and also managed to save Miyu as well. Awesome work! Kindaichi gets info from one of the miners about the secret of the island and also figures out where Inspector Kenmochi and the Detective Boys are. After meeting up and ensuring they are fine, Kindaichi chases after Hioki and watches him leave using a prepared boat. Kindaichi then uses the Detective Badge to call the 'caller' to send a boat over to pick them up. Later, at the port, he meet Conan for the first time (this makes so much more sense that the coincidental meeting), and notices that the boy is a little strange. Superintendent Akechi apparently piloted the boat[I was partially hoping for a 'learnt in Hawaii' line... Akechi squashed my hopes]. They head back to the touristy Twilight Island. {If you haven't noticed, different plots for the two parts}
When they return, there's the reunion of Kindaichi and Miyuki. Cue adorableness.
Later, they learn that people are invited to Hotel Rohage by Hioki. I didn't like the sudden introduction of random new characters - I actually wanted more of the old characters/suspects to be in this murder mystery. Sadly, the creators of the story apparently only introduced Mayor Hioki now. [My personal theory was Shigure was Mayor Hioki - proven wrong] There is a murder in this hotel and the trick involved dominant hands. The left-handed or right-handed thing. At first, I didn't like the trick as there was the possibility that others would also die due to the poison if someone just used a different hand, but when you realise that the culprit didn't really mind extra deaths, it made sense. Now my issue is that I have no idea when the culprit had the time to apply the poison...
Throughout the investigation, notice all the times Kindaichi helps Conan to get out of sticky situations... You know he suspects something is off, which is wonderful~ [Yes, Conan needs more allies]
When the culprit is revealed, who is also Mayor Hioki, Hioki Ryuuhei appears! He's the son of Mayor Hioki, that's why they have the same surname! I didn't notice until he pointed it out... He kidnaps his dad and drags him to the Hidden harbour.
At this point, Conan heads off to chase Asami, who has gone to the other island. Leaving Kindaichi alone for the final showdown with Hioki. Except that Conan calls using the transmitter once more to discuss case details. At the end of the discussion, Kindaichi reveals that he figured out that it was Conan helping him the whole time! WONDERFUL! THIS SHOULD OCCUR MORE OFTEN!
After the relevation, Kindaichi heads to the hidden harbour. You are given a scene whereby Hioki sinks a ship with the gold as funeral fireworks - a very sentimental act for a guy who's been our greatest enemy for Kindaichi's half of the game. Hioki's backstory is revealed, and you realise that he's been obsessed with revenge for the past 25 years. He's a really sad character that doesn't understand that a small part of him wants to stop. It takes Kindaichi, Miyu and the late Misa to convince him to drop his revenge plan. At the end, you can tell that the bastard that been making Kindaichi's life difficult actually feels a kinship with the detective... He basically ends with saying "I wish you were here 25 years ago".
