This one is kinda short, but I had fun with it!  For this headcanon meme.

• Izuku DMs. This is law.  He’s very new to it, because he liked the idea before UA but he didn’t have enough friends to actually do it.  However, he’s not the origin of the UA D&D group, because it would never occur to him to actually propose it to people.  It was actually Uraraka’s idea, because Uraraka has great ideas.  Ask anyone.  She gently bullied Iida into coming along, because she believes Iida needs some fun in his life these days, and shamelessly wheedled Todoroki into it, because Uraraka might not know Details but she knows that Todoroki needs friends, like, yesterday.  Todoroki invited Momo, because Momo looked interested and he panicked about Uraraka’s instructions to “invite whoever”, and Izuku invited Shinsou, because Shinsou also needs friends and Izuku has a good sense for that.  Izuku shyly offered to run the campaign and Uraraka agreed on the spot.  This was a good decision–Izuku starts a new set of notebooks for the campaign and fucking kills it as the DM.  
• Everyone is on an honor code not to use their quirks to fuck with anything, if relevant.  Shinsou is actually very good about it.  Uraraka keeps making her dice float away when she’s tense about a roll, though, so they added a strict rule that only rolls on the table count.  Also, whenever Momo makes them new dice (if they lose one), she has to prove they’re not weighted with a cup of salt water before they use them, because Izuku is very serious about games of chance.
• Uraraka is a half-elf ranger with a profound and sincere disregard for what one might consider “classic elven manners.”  Iida is a dragonborn paladin–he was going to be a human paladin, lawful good, but Uraraka begged him to be an interesting race and he agreed.  Todoroki is a little bit of a shit, because he sits down and immediately says, deadpan, “I would like to be able to throw fireballs.”  He ends up playing a tiefling sorcerer and has a pretty grand time with it.  Momo plays an elf rogue and skill-monkeys her character into oblivion until Izuku learns to dread her asking “can I make a check for that?” Shinsou is the party healer, an aasimar cleric who actually does the healing thing and is vastly underappreciated, because these children have never played D&D before and they have no idea how rare a party healer who actually heals is.  
• All D&D parties have a basic life skill that defeats them on the regular.  No one in this party can make an Insight check to save their fucking lives.  Momo’s Wisdom is low, the only stat she didn’t roll above a 14 on.  Shinsou is the only one with a good Wisdom and he has a borderline unnatural ability to critically fail Insight checks.  Everything else is fine!  All the time!  But one time they have a fifteen minute conversation with the campaign Big Bad, and at the very end of it all Shinsou says “I’d like to roll an Insight check,” rolls a one, and Izuku takes a deep breath, lets it out through his nose, and tries very, very hard not to grin when he says “You really can’t get a read on him, but he seems pretty nice.”
• They spend the entire campaign thinking that Todoroki is the only one with a kind of weird sense of humor, in which he modifies his entire character to specialize in fire magic even though, you know, Todoroki is still Working Through Some Shit.  Then when they’re all like level 17, Shinsou calmly shuffles through his cards and says, “I would like to use my amulet, which allows me to exchange one cleric spell for another class spell of the same level, once a week, to cast Dominate Person on the king at seventh level. He’s going to need to make a Wisdom save of 22 all told.”
• There’s a beat, and the sound of dice.  “Well, he didn’t fucking make that.  So, you mind control him?” Izuku asks, exasperated.
• Shinsou smirks a very little bit and says, “Actually I’d like to brainwash him,” and the entire table loses their fucking minds.
