A/N: This has quite a few inspirations.. Like a sort of dream I had, Dear Dumb Diary and The Case of The Missing Kotsu. Also, Ginkotsu is difficult to write...

In this AU, Renkotsu and Jakotsu are twins. They're all around 16 and there is some kind of implied Bankotsu/Jakotsu.


Renkotsu sat at a small, circular table outside of the coffee shop, thinking. He looked down at his book, which he had recently finished, while he waited for his brother to show up. He was likely taking so long due to the school event coming up.

Their school, which was called Lilac Obsidian School, had said event, The Academy of Interests, every year. All the clubs in the school, which were a lot like classes, made things for it and then sold them, which gave them the funds to keep the clubs running. It was a lot like a bake sale, though only two of the clubs sold things that were edible. Renkotsu had never been particularly interested in the event or the clubs, but this year he had been considering joining one of the clubs.

There were quite a few different clubs in the school, though there were many Renkotsu wasn't interested in. He considered joining the literature club, as books were interesting. Though, as he thought about it, it seemed like it could get boring quickly, especially if they didn't have any good books.

Metal shop was an interesting club. It seemed to be one of the more unpopular clubs, compared to the Art club or Gardening club, though Renkotsu wasn't sure why. There was also Music club, which he thought Jakotsu and Bankotsu were in, though he wasn't sure as they were in multiple clubs.

His thoughts were interrupted when Jakotsu, his brother, showed up, alongside Bankotsu and Suikotsu, who they were friends with. He figured they just got out of their club meetings, which they had a lot more of lately. They sat down at the table and started a conversation.

Renkotsu was quickly distracted by the conversation, which turned into a discussion about a variety of different things, from movies and books to all kinds of things about weapons, especially that of swords or cannons. The school event came up a few times, as well, as they were all going to be participating.

Suikotsu had to leave, eventually, presumably to study. Renkotsu continued talking with Bankotsu and Jakotsu about various things, including the event.

Although his train of thought was lost before he decided which club to join, Renkotsu had decided later on in the day.

It was an obvious choice, but he had still put a lot of thought into it.

The next day, Renkotsu joined the Metal shop club. He sat down as the teacher, Totosai, briefly explained what they were doing in a way that wouldn't make as much sense if Renkotsu hadn't known anything about metal. But Renkotsu had done a lot of research on metal while he was researching robots, so he knew a bit about it.

Knowing things about metal, however, was only one of the steps to understanding Totosai, he assumed after a brief conversation.

The club was more interesting than some would expect. Totosai was an odd guy. Sometimes he did questionable things that didn't seem to make sense. He seemed to know a lot about metal, however, and was undoubtedly skilled at what he did. He had made part of a keychain, almost like a demonstration, Renkotsu had to admit that it was incredible.

They learned how to shape metal, weld, cut, solder and make things. It was a fascinating process.

Bankotsu was in the Metal shop, too, though he didn't seem to find it as interesting as Renkotsu did.

There weren't that many students that seemed to be listening to Totosai, Renkotsu had noticed, aside from himself and a few others. But the instructions seemed undoubtedly important. Totosai was a professional, after all.

After school, Renkotsu walked towards the coffee shop, Le Café de Mukotsu, to meet up with the others. They often all went there after school, though today it mostly seemed to be just him and his brother, Jakotsu.

It was raining today, though not that much at the moment. The drops of rain fell gently, landing in the puddles of water.

It seemed like a good day to sit at a table inside the coffee shop, so they went inside to find a table.

Once they sat down at a table, Renkotsu started a conversation.

"I joined the Metal shop club." He said as he opened a book, figuring that'd be a decent topic. Jakotsu adjusted his scarf.

"You finally joined a club?" He replied, "Jeez, it sure took you long enough."

Renkotsu ignored him, as he started reading the book he brought.

"Anyone interesting in it?"

"Not particularly." Renkotsu answered. He hadn't been paying a lot of attention to the other members, as he had been more interested in learning.

Jakotsu didn't reply, seeming bored as he drank his coffee. After a few minutes, he asked, "Any hot guys?"

There was at least one person in the Metal shop club that Jakotsu would find 'hot', but he didn't bother mentioning that.

"I wouldn't know, I wasn't looking at them."

"Hmm," Jakotsu said, sounding uninterested, "You should."

"I'll keep that in mind."

"Okay," Jakotsu was looking out the window, staring at nature, clearly bored, "You should."

It seemed like there wasn't a lot to say at the moment. Renkotsu continued reading his book.

As time passed, Renkotsu continued attending Metal shop club. He seemed to be good at it, as Totosai was trusting him with creating something for the event.

They were making all kinds of interesting things for it, such as keychains, magnets, jewellery and stones. Renkotsu found it incredible, being someone who appreciated art.

Everything they had finished so far was beautiful, too, and was undoubtedly going to be even better once they were finished. Renkotsu had already learned quite a bit, despite having recently joined.

They continued working on their projects, hoping to, ideally, make quite a few things to sell at the Academy of Interests. Though it was still relatively far away, they wanted to be somewhat prepared.

Renkotsu glanced at the other members. He hadn't really talked to any of the other members yet, though he briefly considered it.

Being one of the smaller clubs, there weren't that many people. Renkotsu didn't really have an opinion on any of the members yet, as he knew nothing about most of them. He considered getting to know some of them, after all, he'd be in this club for awhile and it'd probably be good to know the other members. Though, he did know Bankotsu, but still. It didn't seem like a bad idea.

Totosai started spontaneously telling a story completely unrelated to the class as they all waited for instructions. Renkotsu wasn't sure what he was up to. Totosai seemed to know what he was doing, but he was strange.

Renkotsu barely understood any of the story Totosai was telling. He attempted to focus on his project, but Totosai was incredibly distracting.

"Gesh," The person next to him said, shortly before telling him, "He's told this one before."

"Interesting," Renkotsu commented, observing as Totosai did.. whatever it was he was doing, "So, this is a common occurrence."

He nodded in reply, "It's not the most unusual one."

"That's slightly alarming."

Totosai was currently talking about his pet cow or something like that. Eventually, one of the students in Metal shop started arguing with Totosai, clearly annoyed at his nonsense. Renkotsu exchanged a brief introduction with the guy before they continued watching the argument.

They continued talking, though they were distracted by whatever it was Totosai was doing.

It was astonishing how bizarre things continued to get. The class ended shortly afterwards, and it seemed they had made some progress in their projects for the event, despite being distracted by Totosai.

Ginkotsu seemed like an interesting guy, too. Their brief conversation was nice.

Renkotsu thought about what had just happened at the Metal shop club later on while he walked home and he quickly got lost in his thoughts.

The previous events were interesting, to say the least. Renkotsu still wasn't quite sure what Totosai had been doing, and he didn't expect he would anytime soon.

Metal shop club was undoubtedly one of the most interesting clubs, Renkotsu had decided. Aside from Totosai's shenanigans, which were surprisingly entertaining, the whole process of creating things in the Metal shop was fascinating. It was an amazing club.

Aside from the previous events, there were a lot more things to think about, some were even about the Metal shop club and the upcoming school event.

Renkotsu had quite a few important things to think about, especially with the event, The Academy of Interests, approaching quickly. Like all the things he wanted to make for said event, for example. He had a few ideas of things to make, and that was something important to think about.

Renkotsu shortly arrived home, still deep in thought, thinking about various things, though most things involving the event.

This was the first year he would be participating in the event, and it would arguably be one of the more interesting ones.
