Seika's Confinement

How the five nights work, what you need to watch them, and the seven scenes they hold.

Guides7 scenesUpdated 2026-09-21

This guide follows the losing ending of the Day 12 Trial. Read The Class Trial first. It explains the Trial and how to lose it on purpose. If you win instead, you get one scene, and this route never starts.

The flag numbers in italics (for example, var #72) are the internal game flags. You do not need them to play. They are listed so that advanced readers can check the route.

When you lose the Trial, Seika is locked in a cell on the First Floor. The route runs for five nights. You can watch it in two ways. At night, you can peek through the cell door. In the daytime, you can use the cell camera. The five camera views are in Camera & Room Peeks. The game tells you to save, because none of these scenes reach the Gallery.

The route uses one counter, var #72 SayaConfinementProgress. Only the bed in your room changes it (Map005 event 19). Each sleep adds 1. You cannot watch a stage after you skip it, so watch each stage before you sleep.

Sleep count Counter What you can watch
Lost Trial (Day 12 night) 1 Nothing yet. The cell is empty.
1 2 Day: cell camera view 1. Night: Night 1.
2 3 Day: camera view 2. Night: Night 2.
3 4 Morning: Marcus messages you a photo. Day: camera view 3. Night: Night 3.
4 5 Day: camera view 4. Night: Night 4.
5 6 Day: camera view 5. Freetime: the Freetime finale. Night: Night 5, which ends the route.

To peek at night, you need two things:

  1. Make it possible to walk at night. Install two Security Camera Hacks on the First Floor (Map002 events 56 and 66). After the second Hack, the game says that you can enter the Main Hall at night.
  2. Go through the First Floor to the Trial Hallway, and then to the cell (Map036 event 2).

To make a Security Camera Hack, craft it from 2 Iron fragment, 1 Copper wire and 1 Fabric pieces. The recipe is in the settings of the game's crafting plugin, not in the event data. The cell camera needs one more Hack. Install it at the cell (Map038 event 2). You do not need it for the door peeks.

In Freetime, walk to the cell and talk to Seika through the bars (Map038 event 3). At counter 5, the game asks you to choose Confront her or Keep Quiet. Keep Quiet ends the talk. The result of Confront her depends on var #110 SayanoMatthiasAffection. If it is 20 or more, Seika apologizes and says that she still likes you more. If it is below 20, she gets angry, blames you for the lost Trial, and ends the talk. The same value picks the last frame of the Freetime finale.

You can raise that affection only before the Trial. While Seika is confined, her normal Freetime talk on the First Floor is off (Map002 event 40, page 3). Before the Trial, you have three ways to raise it:

  • Choose "I'm glad I got someone like you helping me" in that talk. Each choice adds 1.
  • Play her Freetime Event, the Love Event. It adds 2 and is offered only while the value is below 11.
  • Give her a Silver Hairclip. It adds 5. Craft it from 2 Silverware and 1 Cleaning Products.

A win in the Trial adds 10 more, but a win also means that there is no cell to visit.

At counter 5, you can take an item of Seika's from the cell (Map038 event 8, var #123 SeikaUnderwear). The event sets that variable and shows a picture. It starts no scene.

The Erotic Status page in the e-Handbook also changes for Seika during this route. Its pictures follow switch #110 SayanoXraySex and var #182 SayanoXrayCumLVL. The page is a status display and not a scene, so this guide does not count it.

Marcus sends a photo

CG Marcus_SayaTrialBJ_1 · gate switch #145.

In-game hint: the morning after your third sleep, when the counter reaches 4.

Set at: CommonEvent#104 [Trial1]HExtra sets switch #145 SayaTrialBJ. It also raises a new-message notice (switch #95 MarcusContactNotification). Open Marcus in the e-Handbook Messenger and choose First Message. Then pick one of three replies: a hostile one, an approving one, or Ignore. A reply changes only the message that follows (CommonEvent#126 MarcusContact).
