Follow these steps to get the “The Story Of The Blue Butterfly” trophy/achievement.
Step 1. First, play through the game all the way up to the point where you talk to Sophia in chapter 11 while picking every option that boosts your humanity (list below).
In Chapter 2 > Inside The House On Elysion Boulevard finish the Weeping Woman’s side quest and pick the “She’s A Cute Baby” option at the end. (Guide Here)
In Chapter 2 > Krat City Hall Answer the phone before crossing the bridge and pick the “Human” option.
In Chapter 4 > Moonlight Town pick the “Give The Stalker’s Greeting” option (you will only be able to do this if you defeated the Survivor boss in Chapter 3).
In Chapter 4 > Path Of Misery use the Pray gesture (obtained by finishing Cecile’s side quest in Chapter 4 > St. Frangelico Cathedral Chapel) at the statue found in the small building that you get to just before opening the double door to the cathedral bridge.
In Chapter 4 > St. Frangelico Cathedral Library follow the main path until you see a lift on your left. Use it to find Alidoro at the top. Talk to him and pick the “Venigni Works” option. Then, head to Chapter 3 > Workshop Union Entrance, head up the stairs and enter the small room on the left to find Alidoro again. Talk to him and pick the “Elysion Boulevard” option.
In Chapter 5 > Malum District you will come across a ringing phone on the main path just after the large area with the bonfire, elite enemy and enemies on the rooftops. Answer the phone and pick the Candle option.
In Chapter 6 > Rosa Isabelle Street Culvert finish Julian’s side quest and pick the “I Saw The Message She Left, Saying She Loves You”. (Guide Here)
After Chapter 6 and finishing Julian’s side quest, return to the hotel to talk to Polendina near the fountain and select the “Show The Wedding Ring” option.
After Chapter 6, talk to Antonia and pick the “Of Course” option.
In Chapter 7 > Grand Exhibition Galley follow the main path until you get to the rafters. As soon as you get to this area, look left and go down the ladder to find Belle. Talk to her for her to move to the hotel (make sure you do this before defeating the chapter 7 boss).
In Chapter 7 > Grand Exhibition Gallery you will come by a ringing phone on the main path (just after the area where the robot smashes through the gate). Answer the phone and pick the “Egg” option.
After defeating Champion Victor (chapter 7 boss) pick the “Hope Of A Cure” option.
After defeating Champion Victor, return to the hotel and talk to Polendina. Then, talk to Giangio (found in the hotel in the room to the right of the Gold Coin Fruit Tree) to get the Cure For Antonia. You will then have to take the cure to Polendina and select the “Use The Cure” option.
After chapter 7, talk to Eugeine to get the Four-Fingered Glove.
On the main path of the first part of chapter 8 you will see Alidoro. Talk to him and give him the glove. Then return to Eugeine and pick the “He Was Happy” option.
After Chapter 8, approach Antonia at the hotel for a short cutscene that will boost your humanity (only available if you give her the cure).
From the Chapter 9 > Krat Central Station Street Stargazer, go through the arch and continue until you get to the cliffside. Here, go left to find a ringing phone. Answer it and pick the “Ergo” option.
After finishing Chapter 9, return to any of the previous phones and answer it. Select the “No” option and open the box (only if you got the previous 4 keys).
After finishing Chapter 9 and talking to Antonia on the top floor, go downstairs and talk to Belle. Accept her side quest and head to Chapter 9 > Krat Central Station. Here, go through the shortcut gate on your right and down the stairs. At the bottom, turn around and enter the train under the stairs. Inside talk to the NPC. Finally, return to the hotel, talk to Belle and select the “He Was Killed In Action Fighting A Puppet” option.
After defeating the Black Rabbit Brotherhood boss in Chapter 10, return to the hotel, talk to Venigni and select the “I Couldn’t Hear” option. After that, talk to Venigni again, go to the hotel Stargazer and listen to the King Of Puppet’s Message.
From the Chapter 10 > Relic Of Trismegistus Combat Field Stargazer, go through the cave and talk to Alidoro. Here pick the “Attack Alidoro” 2 times (you will only have this option if you have enough humanity) and kill him. After that, return to Eugeine at the hotel and pick the “I Think He Was Just A Talented Staker” option.
At the very start of Chapter 11, examine the red statues in the sand near the first stargazer.
In Chapter 11 > Arche Abbey Outer Wall, open the final trinity door (found at the bottom of the area with the 2 elevators and multiple floors). Inside, talk to the NPC and select the “Human” option.
Once you get to Sophia after the Laxaisa boss, select the “Giver Her Peace” option. If you have high enough humanity your hair will turn gray. Before doing this, if you have missed any of the above I recommend listening to as many of the records as possible (in real-time) this will boost your humanity a little more.
Next, get to the end of the game, talk to Geppetto and select the “Refuse” option. You will then get the Rise Of P ending after defeating the Nameless Puppet boss.
After the credits, DO NOT enter NG+. Then, at the hotel, grab the letter from Geppettos desk on the top floor and read it to get the trophy/achievement.
