From Degrees of Lewdity Wiki

Sirris the science teacher is the first of five teachers within Degrees of Lewdity. Their role serves as the player's science teacher, as the job title suggests. They teach at the local Oxford Street School and are the parent of Sydney.


Sirris's description will remain consistent, regardless of what sex they are determined as. They are described to be calm and patient, which can sometimes lead to a disordered class.

First Meeting

The player first encounters Sirris as the first class of the day. They are the first teacher the player comes across. If the player is late, Sirris will mark them for their tardiness - adding Delinquency. Additionally, should the player be found not wearing a uniform when entering the classroom, Sirris will tell them that they are unable to teach them while they are dressed like that, and refers them to Leighton's office to find a spare uniform.


Sirris can only be found within their science classroom between 9AM to 10AM. Science class is the first class of the day, starting at 9AM. As such, there are many events that take place within their classroom.


Sirris' relationship with the player tends to remain the same, unless the player acts as a school delinquent - lowering all teachers' opinion of them, including Sirris'. Although, during the Science Fair, they will feel proud of the player not only completing their lichen project to the best of their ability but also winning with it as well.

Like all other teachers, Sirris will disapprove of the player being late to class, swiftly giving them detention.

The player has the option of confiding in Sirris if they have the "Disassociation" trait from induced Trauma.

Note that it is currently impossible to initiate a lewd encounter with Sirris.


Note: The following events are not to be considered as a full, comprehensive list of Sirris' interactions in the game - but more rather their most notable interactions. As such, minor events may not be listed below. However, more interactions will be listed below as the character remains in development.

As Sirris is primarily found at the school, they will make many appearances within their own science classroom. They will serve as the player's science teacher while attending there, remaining forefront and center in the role. Interactions with them will tend to involve teacher-student interactions, such as helping the player study better and making sure the player is behaving in class.

However, they make an additional appearance when the player participates in the science fair. They are one of two judges, with the other being Leighton.

Science Class

Sirris' duty as a teacher may go a bit further into perverted education than other teachers do. Some may be more innocuous than others. For example, they may:

  • Call the player or another student to the front of the class and talk about various bones and organs. They point to parts of the player's (or student's) body to demonstrate their locations. After a while they thank the player, before sending them back to their seat.
    • Alternatively, they may instruct the player or another student to strip for the sake of learning. This may upset the student, or alternatively make them more eager. They may learn of the student's "secret" (they are crossdressing) and instruct them to sit back down almost immediately.
  • Show the class an "educational" sex tape. This is noted to be more amateur, and graphic - not leaving out any detail for any viewer. Nonetheless, Sirris seems to be unphased by this, merely thinking of it as sexual education. The player may suspect that one of the participants is Sirris themselves, although this is left up to interpretation.

Leighton's Inspections

Leighton will enter the classroom on specific days of each week, and tells Sirris to take a break. Sirris will then take their leave. Leighton will continue with their mandatory "health inspections" as a guise for their perverted desires.

As this is taking place, Sirris will remain in the staff room, taking a break. If the player chooses to run out of the lewd inspections, they will head to the staff room and remain there until the inspection is over. At some point Sirris decides they want to check up on the class to see how they are doing, before returning back to their classroom. The player will accompany them if they are with them, otherwise Sirris will return to the classroom - oblivious of Leighton's dirty activities that just took place.

Science Fair

After attending the science class for a bit, Sirris will eventually inform the class of the annual science fair that will take place soon. From here on out you will approximately have one month to start and complete your science project. It is entirely optional, however - but it will add large bonuses, depending on the project, if you do participate.

Should the player complete any project, Sirris will be left impressed - even admiring the player's creativity for their phalli project. They will be most pleased with the player's lichen project above any others. If the player manages to win, Sirris feels proud of the player.

It bothers some students that I'm the son/daughter of a teacher.
— Sydney, on how they feel about being Sirris' child

As the son/daughter of the school's science teacher, Sirris' relationship with Sydney is that of a typical parent and child. They'll frequently stop by Sydney's counter to check up on (and embarrass) them, often ignoring the player.

Sirris will constantly encourage their overworking child to cut loose, complimenting them should the player convince them to wear contacts or get their hair done. They're also fully supportive of Sydney's friendship with the player, even at high Delinquency.

Currently, Sirris will not mention the player's possible romance with Sydney, even if the player gets promised to them. Given their previously mentioned attitude regarding Sydney and the player's friendship, it can be assumed that Sirris is supportive of Sydney's choice of partner.

In spite of their casual approach to raising Sydney, Sirris' protective side does crop up in the event that Sydney's glasses are broken (either by Whitney, a bully in the canteen, or the player themselves), in which case they simply ask "Who," before asking the player to escort Sydney to the shopping centre for new glasses. If this occurs early in the school day, they'll even excuse the player should they show up late to science class.

The player has the option to flirt with Sydney at the rental counter, in which the player can say the following: "I wonder if Sirris wants grandkids." They do so as they push themselves up against Sydney. If Sydney is Corrupt and in a relationship with the player, they'll confirm that "He/She does," then either tells the player that "I know who I want to make it happen with" (if Sydney is the opposite gender of the player) or "I don't care if I can't make that happen" (if Sydney and the player are the same gender).

Sirris will occasionally check up on Sydney at the rental counter after them showing up for the first time there every now and then. Teasing may ensue, but they are there to make sure that Sydney is doing fine.

They also pick up Sydney from the Temple on Sundays for school. They'll also pick up the player at the same time if they are there too, in which they frown and seem sympathetic for the player's situation.

From here onwards, any mentions of Sydney's "parent" (i.e. "their parent") is in fact Sirris.

Sydney will make many off-hand comments and reference towards their parent upon specific requirements. Most notably, they reference a shop Sirris seems to own on Elk Street.

  • If the player has animal ears from beast transformations, Sydney will remark that they saw some "props" like this when unpacking at their parent's new shop, with them wondering what purpose they serve.
  • Upon closing time, Sydney will say that they are off to help their parent with some work. The player notices that once Sydney exits, they are not heading towards the temple and are in fact heading towards Elk Street.

During the visit with Harper, Sydney will mention that their parent will handle any paperwork from Harper.


  • Sirris is one of several people of interest to exist since the initial release of the game. A full list is provided on the Named Non-Playable Characters page.
  • Sirris seems to be more okay with the idea of sex, unlike the other teachers present at the school such as River or Winter who act more squeamish about it, or will otherwise try to change the subject entirely.
  • They seem oblivious to Leighton's activities within their own science classroom, continuing the lesson as if nothing happened.
  • Prior to Version 0.3.3 and the introduction of Sydney, it was unknown whether or not Sirris had kids of their own.
  • The name of the Adult Shop implies that Sirris' full name may be Sirris Aubergine, though they may have simply chosen to use a pseudonym for their business.
