Secret ending guide for the Yukari RPG
Akari ending (kamiga version): Meet her on the coast and start her quest to hunt 5 sharks, but do at least 20 before returning. when she asks why are you looking for the Bunny Ring, tell her you like bunnies. She will offer to join the party. You don't need to take her yet, but make sure you have her in the final battle.
Akari ending (remastered version): Meet her when she and Gawr announce the online duel and stay with her to watch the game. Make sure Gawr's fans don't touch her during the attack; make sure the traps are at least level 4 to guarantee you get them. The rest of her questline is easy. When you find out where the Bunny Ring is, come back and tell her about it. Make sure you did all the max health increasing missions and have full health. Let her knock you down with her hug and accept her offer to find another way to walk to bunnies with her.
Kiritan ending: Choose 1cc mode and pick the kiriknives as your starting weapon. Use them as your only weapon and never even buy another. To make this work, you'll want to put all the points into critical chance and upgrade them at Yufu to double the chance. You'll still fail a lot of missions (Akari losing to Gawr in the remaster is heartbreaking) but you will get to the final mission. Have Kiritan join you in the final mission.
Maki ending (remaster only): You have to get the Cool-Cute Meter all the way to cool within 3 days of starting the game and talk to Maki. Easiest way to do this is to do the highest paying quests first and buy the Jam Bando fumos. If you do this right Maki won't start her new Voiceroid series and will accept to join you. Keep her with you the entire game and take her Great Electric Fire ability but don't use it. Make sure to start the final mission while it's raining and then use Great Electric Fire.
