This page covers the later Karin quest Karin: Orochimaru’s Mission.
How to start#
First complete the Help Yuki quest through its final objective, 10. Mission. Then wait at least 5 in-game days.
The protagonist must be in his normal form. Once the requirement is met, Karin’s new quest becomes available automatically. Go to the entrance of Orochimaru’s laboratory.
1. At Orochimaru’s laboratory#
A strange ninja named Kachi is guarding the entrance. The protagonist assumes something is wrong and confronts him.
The first choice matters:
- Get involved — continue the quest;
- That’s none of my business — opens another choice:
- Find out what’s going on — continue;
- Get out — fails the quest.
If you continue, the confrontation with Kachi ends with the protagonist forcing his way into the laboratory. You can either knock Kachi out or bring him inside awake; this changes dialogue but not the route.
Inside, Orochimaru explains that Kachi was supposed to accompany Karin on a mission. Since he can no longer do it, the protagonist becomes Karin’s partner instead.
Trying to refuse at this point does not fail the quest: Orochimaru pressures the protagonist into accepting anyway.
The plan#
The target is a private party held near the restaurant on the following evening. Entry is limited to couples, so Karin and the protagonist must pretend to be together.
Orochimaru wants them to recover a dangerous artifact connected to Hashirama’s cells. The second floor is heavily protected, and the pair must avoid drawing attention until Karin can reach the artifact room.
The optional questions during the briefing only add dialogue and do not change the mission.
2. Wait for the party#
Return home and sleep. The next morning the quest advances automatically.
Continue the day normally. When evening begins, the party event starts automatically and Karin meets the protagonist near the building.
During the conversation before entering, choices such as complimenting Karin or offering your hand only change dialogue.
3. Investigate the party#
After entering, Karin asks the protagonist to gather information while she investigates separately.
Talk to all three available groups:
- Harui at the bar — she confirms that the party is really a cover for business dealings. You may drink with her or refuse; it does not change the route.
- Eve — she openly discusses the artifact and realizes that the protagonist is investigating the party, but does not expose him.
- Mr. and Mrs. Root — they reveal the important security details: disguised ninja are mixed among the guests, and explosive tags protect restricted areas.
The order does not matter. After talking to all three, return to Karin.
4. Get the artifact#
Karin learns that the artifact room is protected by multiple security systems and decides to use the ventilation system.
During Karin’s section, inspect the vents until you find the safe entrance. Wrong vents simply send you back to keep searching.
The mission then contains three navigation/security challenges in sequence:
- move through the ventilation system;
- pass the explosive-tag section;
- cross the laser-protected room.
After clearing them, Karin reaches the artifact.
Meanwhile, the protagonist stays in the party’s “fun room” to keep attention away from Karin. A black-haired guest first gives him a blowjob. Eve later gives him another blowjob while a purple-haired woman plays with Eve, and then the protagonist can have vaginal sex with both Eve and the purple-haired woman, choosing the order and whether to cum inside or outside. A later group sequence involves Eve and Harui taking turns using their mouths on him, with a choice to cum in Eve’s mouth or on their faces. These choices only change the sexual sequence and do not affect the mission result.
5. Find Karin after the alarm#
Once Karin takes the artifact, the alarm sounds and the guards stop guests from leaving.
Back in the party room, search the vents. Interact with the vent Karin used to find her and help her climb down.
The pair cannot leave immediately because everyone is being searched. Karin has to blend in with the rest of the guests while they work out how to hide the artifact. To keep up the appearance that they are a couple at the sex party, the protagonist has vaginal sex with Karin while another guest is still nearby.
The artifact gets tangled in Karin’s clothes, and once they are alone they decide to hide it inside her ass. The protagonist inserts the artifact anally through a short minigame. With it fully hidden inside Karin, they can pass the body search.
6. Leave the party#
After hiding the artifact, Karin and the protagonist get dressed and return to the main room.
A guard performs a search before allowing them to leave. The search is passed automatically if you reached this point.
Outside, Karin thanks the protagonist in her own way, gives him a kiss, and leaves to deliver the artifact to Orochimaru.
This completes Karin: Orochimaru’s Mission.
