Can't believe I'm doing this for you Mitsuro, but I guess kids need to be informed.
This is one of my old memo's from previous investigations :
Persona 4 is an RPG. It's about a group of highschoolers trying to find the culprit responsible for a serial of murders. There's also lots of TVs, fog, shadows, and personas, but you don't really need to know that.
[M] Adachi - the goofy policeman. He
unintentionally gives away confidential police information He makes me coffee.
[M] Chie - a tomboyish high-schooler. She's into kung-fu and loves meat.
[M] Daidara - the owner of a weapon shop. That's all about him I guess.
[M] Daisuke - A member of the soccer club. He's not good with women.
[M] Dojima - The best detective evar! I can be a little strict and moody at times, but I can also be really nice and caring at times.
[M] Hanako - A mean chubby. She thinks highly of herself and loves to mope around with Kashiwagi.
[M] Kanji - Acts tough but loves plushies and knitting. People think he's gay.
[M] Kashiwagi - A teacher who hits on students. She thinks she can compare to high-schoolers.
[M] Kou - Member of the Basketball club. He's cool. Also friend of Daisuke.
[M] Mitsuo - This guy is actually very annoying (in the game). He's sick and follows Yukiko around. What a creep. I've taken him to the police station many times.
[M] Morooka - The teacher everyone hates. He's very annoying. Makes you want to kill him and hang him over the roof.
[M] Namatame - He lost it when his wife died. Now he's like a living ghost or something.
[M] Nanako - My cute little daughter. Very mature for her age.
[M] Naoto - The detective kid. She likes to deduce a lot.
[M] Rise - The teenage Idol. She's happy, flirty and beaming (like every idol). She has a thing for strip clubs (lol)
[M] Shu - A nerdy boy who's only goal in life is studying.
[M] Souji - I'm his uncle. He's the silent protagonist. Badass.
[M] Tanaka - conducts a TV shopping program.
[M] Teddie - Pure and innocent little fellow. He's not very used to the human world. He's beary cute.
[M] Yosuke - Souji's best friend. He's a manager at Junes. Is actually quite a pervert.
[M] Yukiko - Plain girl. She has a weird sense of humor, and can't stop once she starts laughing. Can slap you for no reason.
Hope that helped a bit
