Summary
“You’re so smart it’s no longer human at this point.” Chuuya said, shaking his head.
“Yeah well, me being smart helped you pass math last semester, so shut up.” Dazai snickered as Chuuya tried to protest, but couldn’t because Dazai was right.

Dazai has been homeschooled his whole life. Until his adoptive father Mori goes on an extended vacation and leaves Dazai at Yokohama Private High School as a boarding student.
Dazai isn’t sure what to expect, except that he doesn’t plan to be at the school for very long.
And then he meets his hot-headed roommate, Nakahara Chuuya, who flips his world upside-down.

Summary
“Today we will be making a potion that forces whoever drinks it to enter the mind of another person. It is very easy to mess up this potion. One mistake could lead to multiple bad outcomes. So, I suggest you listen carefully,”
...
Dazai hoped nothing would happen. With a slight feeling of fear he grabbed the potion and sat down. He felt drowsy after a few seconds and he fell to sleep.
or
Dazai becomes victim to a new potion that could let his friends (and teacher) into his mind! how does he make sure nobody finds out about his mission? or any other stuff he doesn't want found out? He can't. can he.
also the relationship tag with dazai and snape is platonic!!! Dadsnape! also only slight blazai :)

The armed detective agency received an interesting case to work on.
A couple was found dead and some parts of their body were hidden all over the house with also some writings, made with the blood of the victims, that hinted at the culprit.
Do they want to be found or are they just making fun of the detectives?
Is it all just a macabre game for them or is there something else?A young girl, daughter of the couple, called the police who, after a week of investigation, realised that it was better to give this case to the agency.
Dazai, Kunikida and Atsushi took the case and went to the crime scene where the young girl was still sitting on the floor and refused to move.
Who is the murder? What are their intentions? -

Summary
‘The young boy went on to tell Sakaguchi a story about his day all while cleverly insulting the older man in the most creative ways possible. Dazai’s words were a little more slurred and a little more sewn together than usual..
‘Dazai.’ Said Oda.
The young boy’s muddied brown eyes swirled with insobriety.
‘Heh, hey odasaku you speak!!’
Osamu turned to who he claimed to be his ‘closest friend’ with a huge grin covering his face, meanwhile Ango held back a sigh and pressed his head on the counter after taking off his glasses.‘Are you drunk?’ Asked oda.
‘Me? Pffft no way!!’’
Or, Dazai gets super drunk so Ango and Oda decide it’s time to take action so they start giving Dazai a bunch of rules he’s got to follow.

Summary
Dazai sipped his tea slowly, enjoying the warmth, his eyes glued to the screen of his laptop, where words flowed effortlessly from his fingertips.
Crafting tales of love, where two men could fall into each other's arms without fear or judgment, came naturally, but his own reality presented a far more tangled and uncertain path to romance. Real life wasn't a romance comedy, unfortunately.
Being gay in Japan was a challenge. Sure, there were TV shows with glamorous gay characters and movies that hinted at same-sex love, but the reality was far different.
The law certainly didn't recognize his love as valid, and the whispers and stares he sometimes received on the street made him feel like his desires were considered an oddity, a perversion.
And then there was his heart, a fragile thing that threatened to betray him at any moment. Who would want to love someone so broken, someone who might not even be around to see the next springtime?
OR
Dazai Osamu needs a blood donor for his heart surgery, and his encounter with Nakahara Chuuya might save his life—and change it forever.
