Since @anastasian-dreamer wrote about Aria I decided to post more info on Info Dropper who Aria is tied with.
—-
Info Dropper is a Japanese hero who lived in Japan most of their life. They have cousins around the world, particularly in Canada. They went to UA alongside Aizawa Shouta, Yamada Hizashi, Shirakumo Oboro, Iids Tensei and Kayama Nemuri.
Info Dropper comes from a long line of people with name based Quirks. Their own, Name Drop, lets them gather info on anyone just by speaking their name. Due to this, Info Dropper developed a habit of giving nicknames as they didn't work when given as such.
Info Dropper was never a true part of the Rooftop Squad but was friendly with them, even dating most of the group. They eventually started dating Iida Tensei permanently, their status as the ‘bicycle’ of the group a well loved joke.
Info Dropper began working closely with Nezu, even becoming his personal student by the time of Oboro’s death.
When Info Dropper graduated, they and Tensei began getting incredibly serious. However, Info Dropper did not truly enjoy the thought of working at Tensei’s agency. A proud person, Info Dropper was struggling to make a name for themself as a hero. Being primarily an investigator, they were often shunted to the side by their fellows or relegated to simply support.
Connecting their name to Tensei would make it worse.
The Fae Court, an international hero organization with its home base in Canada, reached out. They'd worked with some of ID’s relatives before however ID was the first of their family to become a hero. Most went to work in more… secretive branches of the government.
They were eager to have ID as part of their court.
This was a blessing for ID, who'd been afraid of always being pushed aside. Working with the Court would bring them international fame, even if they would be taking on a Court Name. Yet this also brought about the issue of their relationship. They would have to live in Canada full time until their service with the Court finished.
ID debated about it, truly. They would discuss it with their family, particularly their younger brother they referred to as ‘Squirt’, who was interested in heroics to follow in his older sibling’s footsteps. However, they did not speak about it with Tensei.
This is where the problem began. Tensei had been pushing for ID to join his family agency, a ring hidden in his dresser drawer. When he found out about the offer, he was angry ID never told him.
They on the other hand were angry he didn't understand what their no meant about joining the agency.
Tensei offered to go with them to Canada if they chose to do so, but ID knew it would be almost impossible for him to make a career there, as his support circle and even his reputation was based in Japan. Tensei didn't know how to be a hero without that backing, something he didn't want to admit.
It sparked a fight, a nasty one that ended with Tensei making a terrible and messed up mistake of cheating on ID who retaliated by instantly finding a rebound. A young Quirkless woman named Sara who was moving to Canada, someone ID met a few months before that Tensei had been a little paranoid over.
The break up had ID cut contact with everyone but their family and Nezu in Japan.
This would be a terrible mistake, for Sara was not just a woman moving to Canada. Rather, she was part of the Unity Villain Group, a group that vowed to get back at anyone who'd treated those with ‘villainous’ Quirks or no Quirk. Sara hoped to woo ID into joining their cause, ID open about their experiences as a kid where they were called a villain for a creepy Quirk.
ID did not seem invested in their propaganda, making Sara decide to take drastic actions. She ordered a hit placed on ID’s family in Japan, the only survivor Squirt whose Quirk ‘Marionette’ let him control anyone he said the name of for five minutes. A perfect recruit as they planted evidence to suggest it had been discrimination that claimed their parents lives.
ID took Squirt in, but also began looking into the death of their parents, their gut saying it didn't happen as people said. They would find the connections to Unity. Sara, sensing the trap closing in, would kidnap Squirt and take him to the villain’s base. There, the group would torment him, trying to make him use his Quirk as they wanted.
It wouldn't last, ID knowing how to find Squirt as soon as they said his name. Sara had believed it would take longer, as ID would need to sort through the information given to them a bit at a time.
ID however knew their brother to well to not have a large amount of knowledge to get them. As well, they were given permission by the Court to use Trigger to expand their abilities. This was allowed by the WHA, who wanted Unity taken down.
There were side effects, as ID’s Quirk was mental, but they found Unity and Squirt.
The trauma of the event would have Squirt becoming selectively mute, something he would eventually overcome but he would still rarely speak. He would go into Support over heroics in the future.
Sara would be sent to jail, and ID would cautiously reach out to their friends in Japan.
Later on, ID would meet a young teen in the USA who'd they figure out fast had a Quirk based on statistics. They would take in the young girl, far to aware few would be able to help train the sort of Information Quirk.
They didn't expect to become a Bibi out of it but they found they quite liked it.

We then end up having various ways ID can interact with the story. In most of my fics, Aria and Squirt are adults now. In other half planned ideas, they're teenagers. ID though is always an adult, and often paired with Tensei.
