Mirio Togata has a goofy ultra optimistic personality is paired with an exceptionally difficult to master power called permeation. He acts super silly and cracks bad jokes which often makes people underestimate him and he's always has a wide smile on his face, even in bad situations. his quirk allows his body to face through any solid matter and letting his enemy attacks pass right through him harmlessly. the power is dangerous for him and hard to control so he trained rigorously to phase specific body parts that exact microseconds, and he's super determined under all that goofiness. He's best friends with Hado and Amajiki. he's super silly and jokes around a lot often but when he's not, he actually gets serious in battles and is actually very intimidating when he wants to be. He can read rooms better than anyone else and he can easily manage to say no or dismiss people without sound rude which is a lifesaver for Amajiki

Neijire Hado she's a bubbly and endlessly curious free spirit with like a powerful energy, projection, cork. She's naturally kind, cheerful and super super talkative and she shows childish fascination with people's unique physical traits because of her curiosity she can accidentally ask invasive or offputting questions but she means no harm, despite her air headedness she can shift to a calm, focus determination when facing villains, she can convert her own physical vitality and stamina into pure spiraling shockwave energy by releasing small spirals of energy from her feet she gains omnidirectional mobility and the ability to hover and fly. she's super energetic and always jumping around and smiling. her personality is similar to Mirio's considering how they're both, optimistic, and very bubbly

Tamaki Amajiki he's deeply introverted, anxious, personality paired with the powerful quirk called manifest. He's extremely timid, easily nervous and lack a whole lot of self-confidence and self-esteem often hiding his face against the wall when he's overwhelmed or anxious he struggles with low self-esteem in tends to undermine his own massive talents, and how attractive he looks. Viewing his capabilities is critically and harshly. Despite his anxiety, he shows a flashes of true bravery and hold a strong sense of duty. He can physically manifest the characteristics of any food he eats into his own body, such as growing octopus tentacles when he eats octopuses. With training, he can simultaneously manifest multiple non anatomically correct traits. he even has a little elf ears instead of regular ones that people often tease him about, but he gets super shy when they do.
