Hey, everyone who's still reading this! I'm alive. I'm so sorry for not updating this in so long (along with all my other stories... oops); I have no excuses.

Anyway, here's another conspiracy theory, that isn't meant to be taken seriously. It's not quite as crazy as the previous chapter, but I hope you all find it satisfying.

Now, before I start, I hope everyone stays healthy during this outbreak, and to anyone who's sick, I wish them a speedy recovery.

Disclaimer: Bungou Stray Dogs and My Hero Academia aren't mine.

Anyway, the theory for today is...*drum roll*... Are Kunikida and Iida long lost relatives?!

It's clear that these two share a lot of similarities, (it's also been previously mentioned in the first chapter, I believe)** particularly in the personality department, and I wondered, maybe Kunikida is Iida's uncle, or cousin, or something along those lines, as people's personalities may be influenced by the people around them.

Let's begin! I'm going to place down some assumptions for the sake of this theory:

1. BNHA takes place almost directly after BSD timing-wise.

2. Iida is at UA (so he's around 15 years old) and BSD is already over, so Kunikida is in his early twenties (~22-23 years old)

3. The two shows are in the same world.

4. Quirks and Abilities are either the same or similar enough that the common public isn't aware of a difference.

Let's start with some similarities:

1. Both are huge sticklers for rules and schedules. This is very clear from Kunikida's notebook and constant nagging about being "fourteen seconds behind schedule" or something along those lines. Iida is also rather obvious with this from his lecturing of others for minor misconducts (such as Bakugo having his feet on the desk, or Midoriya mumbling to himself during the entrance exam). The resemblance here is a little uncanny.

2. Both wear glasses. I know this doesn't really give any substance to them being relatives, but it is a similarity nonetheless, and I want to be thorough.

3. They both have a strong sense of justice. I don't feel this needs much explanation, but Kinukida and Iida are both men of ideals and have a strong sense of "right" and "wrong". I feel the second part is a little more clearly shown in Iida, as he's still young and hasn't really been as exposed to the world's cruelties.

In BNHA's hero society, the world is more focused on Hero and Villain, it's all black and white, so this sense of righteousness would naturally be more clearly defined in Iida, who grew up in a family of heroes.

Meanwhile, In BSD, Kunikida, while still retaining these traits, is older and a bit more mature about it due to the slightly darker world he lives in; he's seen death and other horrors Iida hasn't really experienced, so he has a slightly greyer view of the world. That and the fact the ADA had worked with the Port Mafia (aka: "villains") under the common goal of keeping Yokohama safe shows a greyer viewpoint in BSD (even if Kunikida wasn't the one to suggest the alliance, there was still collaboration). In My Hero Academia, the thought of a Prohero collaborating with a villain or vigilante seems absurd.

(a part of the reason I feel Stain's Arc is so important is that Stain brings a greyer view into the originally black and white world)

4. Going back to number 1, they also tick rather quickly (at least in the comedic scenes). Some examples of this would be whenever Dazai does... basically anything (how that bandage dispenser is still alive is honestly a mystery...), and when Bakugo also does... basically anything ("Stop calling people "extras" just because you don't know their names!"). It's actually a little unnerving how similar they can be personality-wise, though how they react is a little different (Kunikida strangles, Iida robots).

5. This isn't important and has no relation to this at all, but Kunikida and Iida sound kind of similar...

Now for the differences that make me think he's an uncle/cousin instead of someone closer in relation...

1. The appearances are too different. Kunikida has dirty blond hair and is tall and slim. He also has hazel (confirmation? It's hard to tell sometimes) eyes. While He wears glasses, it's not necessarily proof of relation as many people wear glasses(though, bad eyesight does hold a genetic factor to it). Iida's family is also tall, but they also are broader with dark blueish hair and eyes. As both the Iida brothers took after the father in appearance, I'm going to assume his genes were dominant. Therefore, Kunikida's chances of being a brother to Iida are low.

2. We've already seen Iida Tenya's father in the show and Kunikida bears no resemblance to him, so Kunikida, if he holds relation to Iida, would be related to Iida from his mother's side. This would also make some sense, as the mother hasn't been seen, so her appearance and quirk are unknown.

If Kunikida had an elder sister with a large age gap (as she'd be in her late thirties to early forties), and if their parents married younger, it's possible to be Iida's uncle. Otherwise, if Iida's mother is Kunikida's aunt, Kunikida is Iida's cousin.

3. The powers are nothing alike. Quirks are genetically passed down, and Iida's family has had the engine quirk passed down from Iida's grandfather, the first Ingenium. Assuming the grandfather is Iida's paternal grandfather, Iida's mother would have married into the family. This means she would have had a different quirk, or possibly have been an Ability user. Abilities don't seem to be influenced by genetics, which means Kunikida's Ability could be drastically different and could still be related to the Iida family through his relative's marriage. Assuming the Iida mother is Kunikida's sister, Kunikida would be an in-law to the Iida father and an uncle to Iida.

4. Different surnames. Kunikida isn't married (to my knowledge), so the fact the surnames are different is a rather dead giveaway that their relationship isn't direct. It's possible he changed his name for some reason, but I can't really think of one beyond keeping out of the spotlight.

Conclusions

It is highly likely Kunikida is an uncle/cousin to Iida on the maternal side of the family tree. It's wholly possible that Kunikida and Iida were close when they were younger and, as the older of the two, Kunikida's personality may have rubbed off on Iida.

And that's that! I know it's a little short, especially for how long the wait is, but schoolwork was getting more intense before the whole outbreak and self-quarantining happened, so time was a little hard to come by. Also... writer's block.

Anyway, I sound like I'm making excuses! I hope you guys enjoyed it, though. If you have any comments, feel free to review or PM me.

Good health to all of you, and a speedy recovery to those that already have the virus.

** Sorry, this is an unintentional lie. I got the first chapter mixed up with a plan for a different chapter that I had in my head. It might come up in future chapters, though.
