Just thoughts and obsessions

Baji's NOT an idiot

You can't call Baji an idiot just because he isn't academically smart or doesn't get passing grades in school. Sure, he's stupid when it comes to his studies, but other than that, he's really smart and highly intellectual in every other aspect. Moreover, Chifuyu's the one who's a moron here. In many fanfics and headcanon posts, I saw people writing about how dumb Baji is and how smart Chifuyu is and then talking about how Chifuyu guides/helps Baji to understand things or solve problems. And I'm like huh?!?! Have you not read the spin-off manga yet??? (Btw, the spin-off manga is CANON since it's been made under Ken Wakui sensei's supervision and he's heavily involved with the project...)

The whole manga is about what a big dumbass Chifuyu is and how smart, intellectual, and level-headed Baji is. Heck, Chifuyu's so stupid that this is what Baji has to say about him -

So, yeah...

CHIFUYU is the moron here, NOT Baji.

Also...

Baji's NOT an adrenaline junkie

I'm not gonna share pictures for that as proof. Instead, I'll just add the links to the sites where you can read the spin-off manga. I'll say it again - Baji's NOT some reckless, restless dude who loves causing havoc/chaos any time and every time he feels like it (unlike Hanma, Smiley, or anyone batshit crazy we know from this series). Throughout the story, Baji is shown to be quite mature and sensible as a person and also as a leader. He's more responsible, wiser, and more rational than everyone around him. Sure he gets very energetic and excited when fighting other delinquents, but other than that, he's just a simple guy going on with his everyday life. I understand why people think of him like that since this is literally what wiki tells us -

But he's more than just that...

Instead in the spin-off, Baji is portrayed as a calm, collected, and composed individual in each and every scene he appears, while Chifuyu and Ryusei are the ones shown to be more chaotic in nature who love getting into trouble at every opportunity they get. Also, Baji doesn't speak too much and always observes things around him quietly from the sideline, meaning unlike others, he's pretty observant. He's never once shown to be causing problems for others, but rather, he's the one solving the issues that others cause around him, meaning he's a dependable and attentive person (just like Draken). Not only is he calm and composed, but he also immediately figures out any situation in front of him and then confidently gives orders to the others; just reading the spin-off manga will make you realize how effective Baji is as a leader/1st division captain. And, in that episode (season 1, episode 14) where Mikey tells Takemichi that Baji punches people for no apparent reason, yeah, there's actually a reason why Baji does that and such a thing happened only ONCE in his lifetime (Go read chapter 9 of the spin-off manga and you'll also understand why Baji did that). Also, this is Mikey we're talking about; do you really think he'll give us the correct info? He just dropped that info without any context, and no wonder why Takemichi went like "WTF?" after hearing that about Baji... Anyway, Baji's more like Draken in a way, so to speak, and that's why he and Draken get along really well.

No wonder Baji's spending his birthday afternoon with Draken instead of spending it with Mikey or Chifuyu...

So, in short, Baji is:

Not some rowdy, adrenaline junkie like Hanma or Smiley.

An attentive, compassionate, and dependable leader.

Confident while giving out his orders.

A calm, composed, and observant individual.

Very smart and highly intellectual.

Cautious and doesn't cause trouble to others.

Actually one of the most mature ones in the group besides Draken and Mitsuya.

Baji loves fun and adventure from time to time, sure, but he's NOT an idiotic troublemaker.
