denji†

He has basic and simple desires: His initial motivations are extremely simple and down-to-earth, since he was never able to have a "normal" life. Fulfilled dreams for him are things like eating bread with jam, sleeping in a bed, or simply being with a girl.
He is Impulsive and Naive: Due to his lack of formal education and socialization, he tends to be impulsive, focused on the immediate and immature when making decisions, without fully considering the consequences.
He seeks affection and acceptance: Behind his facade, he is a "love-orphaned child" desperately seeking affection, validation, and a place to feel loved, making him vulnerable to manipulation by figures who offer him what he was denied.
He's Brutal but Empathetic: Although his personality can sometimes be rude and harsh, almost childish, he has also shown a good sense of empathy towards other people, willing to save those in danger.
He is an "Anti-Shonen Protagonist": He is usually seen as the polar opposite of the typical shonen protagonist. His motives are very personal and often selfish, primarily seeking to fill his voids and unmet needs rather than having a grand ideal of noble justice.

1. Obsession and Extreme Attachment (Due to Novelty)
   Exaggerated Reactions: At first, he would be euphoric and act in a very exaggerated way. Having a girlfriend is one of the "normal" dreams he has pursued from the beginning.
   Total Attachment: He would show an almost suffocating attachment. He would do whatever she wanted, mainly out of a deep fear of losing that status and the affection he so desperately craves.
2. Focus on the Superficial/Physical
   Simple Happiness: Given his history, his initial idea of ​​a "great date" or what it means to have a girlfriend would be very superficial and simple: perhaps going to a fancy restaurant (for the food), or just spending physical time with her, fulfilling his most basic desires.
   Ignoring the Signs: Due to his naiveté and lack of emotional experience, he might misinterpret or ignore signs of problems in the relationship. If she is manipulative (as has already happened), Denji would be easy prey if he offers her comfort and affection.
3. Clumsy and Immature Behavior
   Lack of Etiquette: She would act in a socially awkward manner and perhaps a little rude or too direct, reflecting her lack of education and socialization.
   Selfish and Pure Motivations: Although he would love her, his initial motives would still be: "She gives me affection, food, a place to sleep, and a 'normal' life." This isn't malice, but a reflection of the fact that his basic needs were denied for so long.
4. Strong Sense of Protection (Their Good Side)
   Fierce Defense: Despite his clumsiness, Denji is fiercely loyal to the people he cares about. If his girlfriend were in danger, he would immediately transform into Chainsaw Man and protect her with everything he has, without hesitation.
