Ryuunosuke Akutagawa was first introduced as a deadly antagonist who hated the protagonist of Bungo Stray Dogs, Atsushi Nakajima. He has the fatal ability "Rashoumon" that is based on the short story of the actual author he was based on, Ryuunosuke Akutagawa. As one of the strongest ability users and members of Port Mafia, he can be seen fighting his enemies effortlessly and fighting against the Armed Detective Agency.

His only downfall is his wish to hear words of praise from Osamu Dazai and his relentless anger towards Atsushi Nakajima. Here are ten facts you didn't know about Ryuunosuke Akutagawa.

10 He Is A Pisces

Ryuunosuke, or more widely called by his last name Akutagawa, is not only a deadly antagonist, but is one of the deadliest antagonists in Bungo Stray Dogs. He also falls on the zodiac sign or a Pisces. Pisces' personalities are known to be complicated and hard to describe. While they can be empathetic, they can be overly emotional and closed off as well.

This describes Akutagawa well as he can become cold and hot at the flip of a hat when it is about either Osamu Dazai or Atsushi Nakajima.

9 He Hates Baths

No matter if a character is an antagonist or not, they still have things they dislike and things they like. In Bungo Stray Dogs, there are a lot of characters that have likes and dislikes listed either at the end of a manga chapter or online from the official account.

It turns out Akutagawa hates baths, although the reason for this is unknown. It can be explained that since he has to have no clothes in the tub, he cannot activate his ability, so he feels defenseless within it.

8 He Has A Younger Sister

Akutagawa might not look like a family person, but he has a younger sister that is his one and only family. She is a part of Port Mafia and is highly-skilled at hand-to-hand combat. She is a Battalion Leader of Black Lizard and usually wears a disguise instead of casual clothes.

Her name is Gin Akutagawa and they live together, although not a lot of people know she is a female outside of Port Mafia.

7 He Dislikes Meaningless Torture

Akutagawa may be a ruthless person when it comes to trampling on the weak and those he dislikes, but he does have an interesting trait. He prefers killing his enemies in one go rather than make them suffer by torturing them.

This may be because of his past and how Osamu Dazai would frequently harm him through Port Mafia training, such as when he shot and broke his arm.

6 He Was An Orphan Raised In The Slums

Akutagawa and Atsushi were created to be similar, yet in different situations. While Atsushi was raised in an orphanage and was abused by the director, Akutagawa and his sister were raised as orphans in the slums of Yokohama.

While Akutagawa met Osamu Dazai during the Dark Era, Atsushi met him when he turned into a better person and joined the Armed Detective Agency. The way he acknowledges Atsushi is also a reason for Akutagawa's hatred toward him.

5 He Likes Antique Calligraphy And Paintings

Just as Akutagawa dislikes baths and many other things, he does have a surprising thing he enjoys. Akutagawa is a fan of antique calligraphy and paintings. This may be a reference to the real-life Ryuunosuke Akutagawa, who was born on March 1, 1892.

The time period he was born would align with Akutagawa's tastes, such as how he also enjoys tea and figs.

4 He Does Not Know The Name Of The Accessory On His Collar

This is an easter egg and fact that comes directly from the Japanese twitter account of Bungo Stray Dogs. It turns out Akutagawa may wear his outfit, but he does not know what the accessory on his collar is called.

It is called a cravat. A cravat is a short, wide strip of fabric around the neck and tucked inside an open-necked shirt.

3 Rashoumon Can Be Used With Any Garment He Wears

Akutagawa has the ability Rashoumon that is extremely dangerous and powerful, although sometimes his emotional state can make the ability less impactful.

Although Akutagawa is always seen wearing his long, black coat and using it, his ability can be used with any garment he is wearing. Whether it be casual clothes, he can activate it as long as he is wearing clothes.

2 He Shares The Same Birthday With His Author Counterpart

The real-life Ryuunosuke Akutagawa was born on March 1, 1892. This also made him a Pisces and he shares these facts with his fictional counterpart in Bungo Stray Dogs. 

The author of the series, Kafka Asagiri, made sure to do his research as all of the characters' birthdays and zodiac signs fall and align with their real-life counterparts' actual birthdays when they were alive.

1 Rashoumon Is A Reference To A Short Story By Ryuunosuke Akutagawa

All of the characters' abilities in Bungo Stray Dogs are based on a famous book by an important author, sans Ranpo Edogawa, as he is simply a genius.

As previously mentioned, Rashoumon is based on a short story published in 1915 in the literature magazine Teikoku Bungaku that ran from 1895 to 1920. It tells the story of a servant who robs a woman of her robe without remorse and disappears into the night.
