Kunikida Exhibits the Behavior of Someone with OCPD

For number one on the diagnostic criteria "is preoccupied with details, rules, lists etc." in a lot of episodes/chapters we can see him obsessing over routines and schedule.

For number three "is excessively devoted to work and productivity etc." that is supposed to be his thing, he's excessively devoted to work.

For number two "shows perfectionism that interferes with task completion" in that seemingly unimportant season two episode (the one with Aya) he hesitates to help with the bomb threat because it would mess up his schedule.

For four "is overconscientious, scrupulous, and inflexible about matters of morality, ethics, or values" Kunikida follows his ideals to the point that he can't not follow them.

For eight "shows rigidity and stubbornness" rigidity and stubbornness are his main personality traits.

Detailed Analysis

• Reduced Sharing of Interests and Emotions: Ranpo's constant smiling and lack of apparent emotional sharing make it hard to discern his true thoughts and feelings.
• Difficulty Adjusting Behavior for Different Social Situations: His behavior remains consistent regardless of social context, such as acting silly at a formal party.
• Highly Fixated Interests: Ranpo's intense focus on detective work, often to the exclusion of other topics, exemplifies this symptom.
• Significant Impairment in Important Areas of Functioning: Despite his intelligence, Ranpo requires assistance with tasks like riding trains.
• Not Better Explained by Intellectual Disability or Developmental Delay: His high intelligence rules out intellectual disability, and there is insufficient information about his childhood to suggest a developmental delay.

DSM-5 Diagnostic Criteria for ASD

1. Reduced sharing of interests and emotions
2. Difficulty adjusting behavior for different social situations
3. Highly fixated interests that are abnormally intense
4. Symptoms cause significant impairment in important areas of functioning
5. Symptoms are not better explained by intellectual disability or developmental delay

Ranpo Exhibits the Behavior of Someone with ASD

For 1 "difficulty with social interactions and communication" in untold origins Ranpo came to the conclusion that everyone was a stupid idiot and announced that to the whole theater, which leads me to believe he has a hard time with social stuff (sidenote: i would also do that).

For 3 "reduced sharing of interests and emotions" you can't really tell what Ranpo is thinking because he's always smiling.

For 7 "difficulty adjusting behavior for different social situations" after the cannibalism arc at the black tie party we could see Ranpo acting like his usual silly self instead of being polite and fancy(?).

For 8 "trouble making friends or lack of interest in peers" in untold origins it seems that Fukuzawa was Ranpo's first friend.

For 12 "highly fixated interests that are abnormally intense" Ranpo's main topic of interest is detective work, and he talks about little else.

For 15 "symptoms cause significant impairment in important areas of function" despite his extraordinary intelligence, Ranpo cannot ride trains and needs Atsushi to help him.

For 16 "symptoms are not better explained by intellectual disability or developmental delay" Ranpo shows extraordinary intelligence so I think that rules out intellectual disability. And we don't know enough about his childhood for developmental delay.

For PTSD:

For 1 "directly experiencing the traumatic events" Lucy's experience at the orphanage was very traumatic for her, as she was forced to wash dishes in ice cold water every day, and was subjected to physical abuse at the hands of a hot iron poker.

For 7 "dissociative reactions in which the individual feels or acts as if the traumatic event(s) were recurring" in episode ? Lucy had a flashback to the orphanage.

For 15 "persistent negative emotional state" every time you see Lucy she is in a negative state of emotions. Example episode - all of them.

For 18 "persistent inability to experience positive emotions" once again Lucy is very rarely in a positive emotional state.

For 19 "irritable behavior and angry outbursts" when Lucy is a waitress at the cafe she is very irritable and threw a report off the dock so Atsushi would have to get it.

For Dependent Personality Disorder:

For 1 "has difficulty making everyday decisions without an excessive amount of advice and reassurance from others" Lucy doesn't show independence that much because of her over-reliance from the guild.

For 2 "needs others to assume responsibility for most major areas in his or her life" Lucy's dependence on the guild and Atsushi stems from a lack of self confidence.

For 5 "goes to excessive lengths to obtain nurturance and support from others" when Lucy failed her mission of trapping people the guild kicked her out but she begged to be a maid and do labor to stay.

For 6 "feels uncomfortable or helpless when alone because of exaggerated fears of being unable to care for herself" her fear of being alone is evident when she stays with the guild even though she knows they're bad.

For 7 "urgently seeks another relationship as a source of care and support when a close relationship ends" when Lucy was kicked out of the guild she quickly attached herself to Atsushi and the agency.

For BPD:

For 1 "frantic efforts to avoid real or imagined abandonment" Lucy was abandoned at the orphanage which probably fueled her fear of abandonment. She joined the guild because they were giving her positive affirmation, despite her knowing they were bad.

For 2 "a pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation" on the airship Lucy hated Atsushi and wanted him to suffer like she did, but when Atsushi shared his experiences Lucy softened up and was nicer. And when she was a waitress she disliked Atsushi again.

For 6 "affective instability due to a marked reactivity of mood" once again Lucy has a tumultuous relationship with Atsushi, like on the airship she quickly became sympathetic with Atsushi due to their shared experience at the orphanage.

For 7 "chronic feelings of emptiness" when Lucy is kicked out of the guild she begs to stay because she has "nowhere left to go" and it seems as if she tries to fill up her emptiness with others company.

For 8 "inappropriate intense anger, or difficulty controlling anger" Lucy definitely has some anger issues. For example in the cafe she was intent on getting revenge on Atsushi by throwing his reports in the water. And was also unnecessarily mean to him.
