#15 Kougami (Tsujino "Nono" Fumie)

Tsujino is a sheltered, but knowledge hungry woman. Her character traits are almost contradictory, being a very paranoid, and neurotic lady who dislikes doing anything she is not familiar with and out of her comfort zone, and perpetually stubborn on receiving help, yet is extremely independent and possesses a leading demeanor, and incredibly impulsive on matters where she feels like she knows best. She is a bit in her own head, believing that she is the one true ambassador of Voidkind and ignorantly pretending the rise of Void/Host pairings doesn't exist, though she knows very well they are prevalent now.

Tsujino is dowsed with guilt due to her involvement with the Lab Committee and her general foolishness and neuroticism, but she remains dominant in her ideas and has confidence in herself enough to believe that she is a genius beyond all geniuses. Her guilt makes her try to find answers to fix issues she feels responsible to mend, but she gets so into her head in the process that she believes that she knows what's best for everyone, doing things in advance without approval. Tsujino truly believes that she is the only one who has the correct answer, though this all stems from her fixer mentality. She does desperately desire the input of others, but Tsujino can also be a crybaby and stubborn when it doesn't line up with her ideologies.

Her view on people has been skewed due to her defecting the Lab Committee and her paranoia. She believes all people are naturally selfish, and tend to stay stuck in their selfish ways. She herself believes she is included in this category of natural selfishness due to her past, even though her intentions have always been self sacrificial. Her self confidence in herself as a genuine and heartful person is significantly lower than her self confidence in her abilities. She feels terrible for keeping Kougami to herself in hiding, increasing her already incredible guilt, and sometimes can get into a headspace that makes her believe Kougami is only with her because otherwise he would be dead, and not because of a true bond. This is what motivates her to search for the answer to turning Voids back to humans should they have been corrupted, giving those Voids a safe haven and the "true freedom" that they deserve. She thoroughly dislikes the more researched Coexistence Method because she believes it's selfish for a host to hinge on and hog up the life of a Void, and states genetic modification will do better in the long run, fitting of her mad scientist status. The Parasite Voids currently melding in with humanity have clearly displayed that they like being themselves, and like their current identity and bonds, showing Tsujino's impulsive savior complex and inability to accept other's choices. She grows to learn and accept that the Coexistence method and genetic improvements should work in tandem, and not divided; she realizes now that the psychological growth of Coexistence and the physical accomodations of genetic improvements bring essentials to a happy life for the Parasite Voids.

Tsujino can be talked out of her impulse, but she just has never experienced the support of such. When she is in situations of support, she can be emotional and overreactive out of fear. However, it will make her reflect on her issues, and less scared to let go of her ideals. She gets this treatment through the other heroines and begins to warm up to differing ideas and starts improving methods beyond her own biases, like the Coexistence method, while also using geneticism to improve small but helpful enhancements like EXS rationing, strength, and et cetera. Her biggest project nowadays is trying to make a serum that'll reduce Voids constant craving and desire for EXS, and helping them to eat a normal amount like holy fuck they dont need 500 steaks for dinner

After her reformation and earning of the heroine status, she still is anxious about small things but displays more confidence in making her ideas more diverse. Whenever the heroines need to do something, this girl will always have a plan if none of them do! She is less afraid of the outside, shedding her tendencies to shelter herself, and slowly becomes more confident in herself not just with her abilities, but with Tsujino, as a person. She is less fearful of her expressing her ideas to others, including situations of them getting shut down and turned into a compromise, but if she really feels like she is making a point, she will defend her thought process. At the end of the day, Tsujino is just a sheltered nerdy girl who is trying to become more honest with herself little by little.

When around the heroines and Kougami, she tends to be clingy as a way to emote her shock of having a group that is truly there for her, often being really touchy in ways that would look unwanted to a normal person. This seems to be from Tsujino having zero friends growing up. She tries her hardest to impress them (failing miserably) and return the favor for saving her from what felt like a lonely world, especially towards Nodoka.
