Ritsu's internal conflict in 'Mob Psycho 100' is a goldmine for fanfiction writers on AO3, especially when paired with Shou Suzuki. The tension between his desire for power and his moral compass is often explored through their dynamic. Many fics delve into Ritsu's guilt over his past actions, juxtaposing it with Shou's chaotic neutrality. Some stories frame their relationship as a balancing act—Shou's recklessness forces Ritsu to confront his own suppressed emotions. Others focus on Ritsu's envy of Shou's freedom, contrasting it with his own rigid self-control. The best fics don't just rehash canon but imagine how Shou's influence could either destabilize or heal Ritsu's psyche.
One recurring theme is Ritsu's fear of becoming like his brother Mob, yet also craving that same purity. Shou, as someone who rejects societal norms, becomes a mirror for Ritsu's hidden desires. I've read fics where Shou's teasing gradually chips away at Ritsu's defenses, leading to raw emotional confrontations. The psychological depth comes from Ritsu's duality—his calculated exterior versus his turbulent inner world. Writers often use Shou's unpredictability to expose cracks in Ritsu's armor, creating moments where he either breaks or rebuilds himself stronger.
