Ok, so we already know the details of Yosano's ability. We don't need to go over that. We know that she helped out soldiers during "The Great War". The interesting thing is that we don't know how she found out about her ability. Did she just one day find a dying person and then heal them?
My personal theory is that Yosano had a very violent childhood. She probably grew up in the part of the city that the mafia controlled. She probably found herself getting attached to a friend or a parental figure, and one day, they almost died. She probably healed them, and while they celebrated, someone from the mafia saw and told Mori. The person was executed, and Mori took her in, telling her that she'd have a home, that he killed the person who killed her friend (sorta Akutagawa parallel). She'd be forced to rely on him, and when he asked her to go to war, what choice did she have?
Another theory is that her parents were medics during the war. She didn't know about her ability until she was around an almost dead person because of her parents' career. Then, she healed them, and then was scouted by the mafia.
I doubt it's the second, because the majority of the ADA don't have parents (oof), and also if she had parents, and even if they were killed by the Port Mafia, she wouldn't have listened so willingly to Mori until the end. Also, Mori is a "doctor", and maybe he used that to relate to her, saying that he could train her to use her ability to save the most people, as she experienced loss (first theory)
i apologize for the late response! i began writing a response around Christmas time, but i didn't catch up with the manga until last week, so i wasn't sure if Ango's ability had already been revealed and if this was even worth finishing ¯\_(ツ)_/¯ anyway, thank you so much for your kind words!!! i live for praise, keep it coming
i did not have a theory about Ango's ability for the longest time, but i do now, so IT'S THEORY TIME. and you anime-only fans can even read this whole darn thing because no spoilers. hell yeah
POINT ONE:
for starters, i believe everything i've seen so far suggests Ango does not have a combat ability. i believe his ability is something like Ranpo's fake ability, something that gives Ango an intellectual boost
to me, it makes the most sense given his position as a member of the government in the Special Ability Department and the way he acts like a know-it-all. but yes, he's technically a politician. and he's definitely a sharp politician who knows what's what. and he was the port mafia's intelligence agent. so… intelligence. i'm telling you
^look at this guy knowing all the stipulations like a real know-it-all
but yeah, i did not see Ango as a combat ability user. i personally haven’t seen any of the THREE organizations he's worked for give him a combat job. and i mean, look at this:
doing nothing to fight them off. where that combat ability at. probably doesn't have one
POINT TWO:
i think that Ango's ability allows him to spy on people. i think he can teleport himself to different locations. perhaps even just his mind or parts of his body, allowing him to remain hidden and secretive. the evidence is somewhat circumstantial, but nONETHELESS
i'm still convinced that this is Ango's arm:
*this scene wasn’t included in the anime adaptation, for anyone wondering. it was after Atsushi “saved” everyone from the fake bomb. the hand was just there. randomly thrown in, never explained. thanks Asagiri and Harukawa
idk what Ango’s arm is doing behind Naomi's skirt, but the clothing textures and layers match. anyway, i imagine that he spies on the ADA as part of his responsibilities as a Special Ability Department agent
and maybe Naomi has seen the hand before and always thinks it's her brother using Light Snow. no idea honestly
POINT THREE:
actually, this point isn't really evidence as much as it is circumstantial speculation. but yeah, i feel that Ango was never in any real danger when he was tied to that chair (whether or not mimic put him in that chair). it appears that the whole thing is a trap for Oda, but Ango doesn't seem to think Oda would still be on his side
Oda tells him that everything's okay—that he knew Ango infiltrated Mimic for the boss. but that's not true. Ango infiltrated the mafia. he's a traitor. but Oda faithfully believes in his innocence. then Ango, likely out of guilt, says:
so if Oda hadn't come to save him, was the building still going to blow up? my question is, how would Ango have escaped? the Special Ability Department was definitely there, and Ango knew it (i'll argue this). but i don't know if they would have gotten him out of the building on time. perhaps they knew Ango could teleport himself somewhere else?
again, Ango knew the Special Ability Department was there. what with the poison temari ball suddenly rolling out of nowhere. Ango knew about the temari ball. he went out of his way to point it out and then use it to escape with the ability department
In conclusion:
so yeah, teleportation
perhaps this even clued Ango in to the car accident with Dazai? i could possibly see Ango closing his eyes and being able to see someone coming for them (mind teleportation?)
maybe not, but it's some food for thought
finally, i don't know if there's a connection between the rl author's book and Ango's ability. someone correct me if i'm wrong, but I did some reading and it seems that Discourse on Decadence talks about errors in the ways of thinking during war (suggesting that war mentality/traditions are bad). the ability name may highlight that Ango is supposed to be a diplomatic (rather than war-crazed) character in BSD, but idk
