1. The two rings Keisuke uses are actually his dad's and his own ring, which Kenji had made for him before he died. 

2. The reason Keisuke is completely different from his canon self is mainly because of his background. Kenji and he had promised to be best friends forever, but then Kenji's parents didn't like it, so they planned out the accident. Luckily, Kenji managed to find out and save Keisuke at the last minute, though Keisuke still blames himself for that. 

3. There was this one time after Touma and Akinori betrayed them that Peace found a bunch of survival RPGs in an old video game store, so they brought it back and Masaki set it up. After playing it, Misaki had stated, "Wow, I wonder how the characters in that game would feel if put in our situation, because they didn't have it rough at all." Everyone roared in laughter that day, especially Masaki and Keisuke. 

4. After some discussion, Peace decided to let Keisuke completely lead their group. They didn't want to let another Touma and Akinori betrayal happen to him. Upon hearing that, he had teared up and hugged all of them, saying thank you. 

5. Fudou Myouou Boy woke up after Sakura New Town was restored, and the first thing that he asked was, "Where's the chocobo?!"(Keisuke ended up buying him a mountain load because of his pleas.)

6. Keisuke and Masaki had actually been friends since Charlie's case. Keisuke had confronted him before the Agency met Junior and told him the truth about Charlie. After that, Masaki had completely changed with Keisuke's help, and the two became gaming partners. It was actually Masaki who introduced Keisuke to Lightning Speed Age and the VR Game where the group met Shield of Brightness. 

7. The Youmakai had sealed itself off in order to protect itself from Shuka. Another reason why she needed Keisuke; with his strong emotions, he could power them enough to take over the world and Youmakai. (Translation: Good thing Keisuke didn't go over to their side.)

8. Kuuten had actually married Shuka before he killed her father, which is why in this story, Soranaki is part of Shuka. 

9. After a few months, Natshuka finally managed to work out her feelings with Keisuke's help and support, and she joined Gentouma, Hakushuri and Ayame with the restoration. 

10. Ayame was brought back thanks to Akino, Rau, Choiseung and Chenhua's return during the final battle, and she had a depression for a while before Azusa brought her back to her senses. 

11. Peace eventually became an ambassador group between the outsiders (the humans who were moving into Sakura New Town) and the insiders (them). The most popular guides were Masaki, Uchida and Manami because of their friendliness. Masaki had even joked once that while Keisuke was a great leader, he was also one of the most social-awkward ones, causing Keisuke to hit him with a red face. 

12. Keisuke's manga, Masks, which tell the story of an analyst who has split-personality disorder AND depression, was internationally loved after it was accidentally sent to Korea's most prominent publisher, and he was invited to go to a lot of places. Of course, as Peace's leader and Sakura New Town's protector (as Peace had officially called him), he still does his fair share of the paperwork, helping the new mayor, Azusa, as her advisor of sorts. 

13. Peace eventually separated, but they still keep in touch and meet up once a week with Natshuka, Gentouma, Hakushuri and Ayame.
