15 Chill Anime Characters Who Get Tough When Things Get Serious

Updated September 20, 2020 35.2k votes 5.5k voters 128.6k views15 items

Few anime characters display the same personality traits at all times, but not all of them change drastically. In some cases though, the change can be pretty stark. One type of character whose personality does a complete 180 are chilled out, nice anime characters who get serious when they have to deal with conflict. 

One example of this trope is Hatake Kakashi of Naruto, who is normally a laid back dude who goes totally serious when fighting against enemy ninja. There's also Rimuru Tempest of That Time I Got Reincarnated As A Slimewho faces everyone and everything with a smile until he's actually staring down somebody who means him harm. Nezuko Kamado of Demon Slayer might be the cutest thing ever, but if you touch Tanjiro she's a force to be reckoned with.

    Nezuko Kamado - 'Demon Slayer'

    Nezuko Kamado is one of the most adorable anime characters to appear in recent years, and part of that is because of her oddly blissed out nature. Already a calm, sweet person prior to her demonic transformation, she somehow manages to retain her kind personality - with a few added quirks, of course. However, if anybody threatens her brother Tanjiro, the demon claws come out.

    Shota Aizawa - 'My Hero Academia'

    Would you expect that a guy who wears sweatpants to work, doesn't groom himself, and takes naps when he's supposed to be teaching how to be a stalwart hero? Probably not, but that's what Shota Aizawa, the homeroom teacher of Class 1-A brings to the table.

    Most of the time, he's chill to the point where others consider him unprofessional, but he'll throw away the sleeping bag and fight with everything he has to protect his beloved students from villainous attacks.

  • Monkey D. Luffy is a member of the Straw Hat pirates, and if you only saw him hanging out with the rest of the crew, you'd probably think he was a cheerful idiot who would be useless in a serious situation. But while he spends his free time getting way too enthusiastic about hermit crabs, he's a reliable and powerful fighter whenever there's a conflict. He isn't oblivious to the hardships of pirating, he just prefers that everyone focus on the positive and try to live their best lives so that they're fully prepared to face danger when it happens.

  • Okay, so Roy Mustang does get into yelling matches with Edward Elric on the regular, but aside from being a little bit temperamental when it comes to the teenage alchemist, he's actually a pretty easy-going guy.

    But when faced with a real conflict, he drops his flirtatious jokester persona and gets serious. He will not hesitate to burn his enemies to a crisp if there's no peaceful way to diffuse a situation. Good thing, too, otherwise he likely would have been destroyed by a homunculus midway through the series.
