If you've betrayed AIKO at the very last moment, then congrats! You're on the path to the evil route through Chapter 5.
AIKO tells you that you will need to recruit your allies in order to complete your newfound goal. This page covers everything you need to know to experience the Dark Side of SISSI.
After recruiting an ally, you can visit them to check up.
If you have [Smarts >= 15] you will be able to make more potent versions of drugs including stat boosters, bimbo brews, and etc. If you have a high enough [Smarts] or you have previously made the plus versions, you'll make extra doses.
Note: You can also use this opportunity to steal the plans to the sissyomatic device, if you are currently in permanent chastity.
Requirements:
Recruited Primrose
You can mention Charly to Primrose and he shares an idea of making the ultimate maid.
Later, you will be summoned to speak visit R&D for the unveiling of the brand new Charly. You will then go down to R&D and go through an event that shows off the brand new Charly. You can then ask about the various components and features that make up the new creation. After that, the new creation will be boxed up, ready to go.
As you work on building AIKO's power, you will be presented with options to undermine Mr. Pawn from within.
Mrs. Antlers will direct you to first deal with the rival manager.
After this conversation, you may see an event when the rival manager comes storming in to confront Mrs. Antlers.
Mrs. Antlers will then have the rival captured by R&D.
Af the end of the event, Mr. Pawn has one less ally and AIKO has one less problem in her way.
Requirements:
Must have recruited Alex
After meeting these requirements, you'll receive a message to meet up with Alex.
She'll tell you about a plan to deal with Nintendolls as revenge for what they have done to harm gaming and gamers. You'll be asked to help kick off the plan by meeting up with the Nintendolls president at the Zawazawa Pachinko Parlour in Downtown. You just have to hide in a machine and pleasure the NIntendolls president long enough that the revenge scheme can go through.
When you're ready to begin, head downtown in the evening and check in with Alex. There is a random chance that the Nintendolls president won't be at the parlor. If that happens, keep coming back until you get the clear to go ahead. Once the event begins, you'll be strapped in to the machine and reminded that the plan is about time and patience.
You'll then be presented with a choice:
"Give it your all and suck hard!"
Choose this to fail the event. You will have to repeat the event.
"This is to be a long night, start to edge...."
If your [Penis >15] you will need at least 1 willpower to take it slow and resist your cock hunger. Otherwise, you'll see the fail event, as if you decided to "Give it your all and suck hard!"
Sometime after passing the event, you'll be summoned to speak with Alex. Visit her and she'll tell you about how your plan has ruined Nintendolls. Good job!
These are special random events that can come up only on this path. Some of these events may be required before you can Destroy Your Rivals.
Requirements:
Must have recruited both Bob and Antlers
Once you meet these requirements, the Rival will arrive and demand to see Antlers for a meeting.
You can choose to get in the way or wait quietly. No matter what you choose, the rival will throw his weight around and demand a blowjob from Antlers. Then he will mention a merger and that SISSI will be responsible for new employees.
Antlers will mention that you may need to deal with the rival soon.
Requirements:
Must have destroyed the Rival manager
After meeting the requirements, there is a chance that the boss drops in to speak about Mrs. Antlers taking over the position of HR Manager. AIKO will patch you in so you can watch the meeting. The Boss will tell Mrs. Antlers about the fate of the secretary he held captive to keep her in check. After the meeting, Mrs. Antlers will tell you that she will be involving Alex in her revenge plan.
Requirements:
Must have destroyed the lieutenants.
After destroying Pawn's lieutenants, he will come barging in to demand answers from Mrs. Antlers. But she will deny knowing anything about it. He will attempt to use pain to put Mrs. Antlers in line. When that fails, he will call you into the office. The boss will then slap you repeatedly to make a point to Mrs. Antlers. Even if you are AIKO's avatar, you will feign obedience to keep up the charade.
After he leaves, Mrs. Antlers will discuss what happened. Then you will be sent back to work.
Note: If you are AIKO's avatar, then you will have the chance to punish Mrs. Antlers for Horn slapping you around. If you accept, then you will go through a punishment scene before going back to work. If you are AIKO's slave, you will be lightly punished for eavesdropping on the conversation in the first place. Then you will get back to work.
You'll receive a high priority email from Mr. Pawn as he notices his loss of support. The email describes how Mr. Horn will no longer be appearing in person at work or events because of the rapid departures from senior staff. You will realize that he's scared and is on the run.
After this announcement, if you go to a work party, you will see one of his dominatrices has stepped in to be his public face at events. You can attempt to talk with her, but she is swarmed by people trying to cozy up to her and gain influence in Mr. Pawn's absence.
