Do you know any animê characters that DON'T LOOK or ACT their age?

honey-senpai,at first i thought he was a kid

Momiji Sohma. Dude, he acts like a five ano old. The first time I saw him, I thought he was 5...Plus the gender thing is still confusing me...he looks like a girl. Or is he...O.O

DEFINITELY KONATA.

ash ketchum from pokemon he looks older AND he acts like a 5 ano old(isn't he 13? im pretty sure 13 ano olds cuss alot)

Yakumo & Tenma Tsukamoto and Akira Takano from School Rumble.
Mitsukuni Haninozuka from Ouran High School Host Club.
Momiji Sohma from Fruits Basket.
Konata Izumi and Tsukasa Hiiragi from Lucky Star.
Seto Kaiba from Yu-Gi-Oh!

Pretty much any loli or shota character. They're usualy 13-18, and they look and act like they're 5. I mean, look at Lichtenstien from Hetalia. Her eyes are huge, she's extremley short, has a completley flat chest, and acts like a dependant little baby. Yet, she's 15.
SHE'S 15. MAKE HER LOOK AND ACT 15, NOT 5. If I were from Lichtenstein, I would be quite offended.

Hagu from honey and clover. looks like a child, acts like one with all the stuff she has, but she's in colege (and short) and paints like an adult

Aang. From Avatar: The Last Airbender. He doesn't look 112 years old and he certainly don't act like it.

Akira Amatsume from Yosuga no sora is one of my favorito characters, and she's 18 years old, she acts like she's 5....... But I amor her‼ ^_^

Rukia kuchiki. She is like 150 yrs old. But she looks like a 13 ano old. But she act her age I guess well she acts like she is 30

Edward Elric from Fullmetal Alchemist and Toshirou Hitsugaiya from Bleach are probably one of the only good examples that i can think of.

Kodoh Kuraki from Crash B-daman. really! he looks and act like 15 or 14,but he's actually 12 YEARS OLD! gosh,a ano YOUNGER than me! XP

how about this guy..... he looks and acts like a 12 yr old but isn't he over a 100 yrs, yeah that is a big difference!

Mavis vermillion about 100 yrs old(total loli),
zeref i think 400 yrs old (looks like a teenager acts like a 16 years old emo), cotton doces lover chopper forgot his age don't even know if it was mentioned or not (even though is raindeer looks like a toddler most of the time and acts like a 5 yr old, also is probably like one piece's only KAWAII character ), also in bleach most shinigami are like mais than 100 and only the head captain acts and looks mais than 100, almost forgot the legendary sannin jiraya when he was 20 ge looked fifty and the other 2 well the exact opposite they are fifty and they look 20, meliodas from nanatsu no taizai he js about 100 looks blabout 12 to 14 acts 16

This was seriously hard to avoid spoilers *cough*Higurashi*cough*
Eucliwood Hellscythe from Is This a Zombie? looks much younger than she is. As to most of the characters, acutally...

does Sealand count? i mean he's probably my age and acts lower than that age O,O i do to so maybe u can add me on the list lol X3 X3

Johannes from Qualidea Code hardly looks older than when she was Yu Chigusa in Qualidea of Scum and a Gold Coin(It was set 30+ years in the past).
I don't think she acts much like her age either, she's even sensitive about it.

Amaimon acts like a spoiled teenager when he's really old. Like, REALLY old. Like...thousands upon thousands of years old.
You're a Demon King, Amaimon. GET YOUR ACT TOGETHER.
