_This is my OC, his name is Tsushima Shuji who could be considered a alternative versions of Dazai Osamu in numerous alternative universe of Bungo Stray Dog . This is a summarize of Tsushima Shuji life:

_ Firstly, Tsushima Shuji AU is different alot when compared another normal Bungo Stray Dog AU because his AU is the world created from the dream of a sleeping god Cthulhu (p/s: I don't know who this god name will be). He was born in Tsushima family on February 24th, he lives there until 3 years old, then he escape from the place that raising him (p/s: Tsushima Shuji has a connection to the "Book" in his world.  I mean, if he accidentally touched the Book, he wouldn't be mad at stuffing billions of memories like another Dazai Osamu.) . Because, the upper-class people in the family want to sacrifice him (p/s: why he is suitable for sacrifice. What conditions do body and soul of him meet?) for the unknown Cthulhu god (P/s: the upper-class people in the family are all religious fanatic of the Cthulhu god, i guess) to make him become the vessel so that the Cthulhu God can walk on earth without causing the world to be crushed by something of God Cthulhu and then destroyed. Tsushima Shuji wanting to avoid that cruel ending (P/s: Why it is a cruel ending for him?) so he ran away.

What did he do when he ran away?
_ As I had said, he has a connection to the "Book" - the origin of all Bungo Stray Dog world. The "Book" suddenly appear right next to him when he was imprisoned in the room and waited for sacrificial ceremony, so I think he use the "Book" special ability by wrote a story that Tsushima Shuji reasonably succeeds in escape on the "Book".

What did he take with him?
_ He take the "Book" with him.

Where did he go?
_ There's a voice in his head telling him to go into Yokohama.

Is there anywhere or anyone he knew that could help him in this situation?
_ The book is an item that only Tsushima Shuji can see and touch, and the only thing he can rely on to avoid the Tsushima clan's pursuit. So he found a way to escape while drawing blood from his finger to make ink and write more stories about Tsushima Shuji's ability to escape successfully.

How did he survive?
_ He managed to escape by deliberately letting a trafficker look at him and put him in a boat to go to Yokohama by using the "Book" to confuse his appearance and identity.

If he escaped so easily, how did no one find him?
_ No, the progress escapes of Tsushima Shuji is difficult. To catch him more faster, the religious fanatic pray to the unknown Cthulhu god some special ability to locate him. If Tsushima Shuji don't have the helping from the "Book", no matter how smart he is, it's only a matter of time before he gets caught.

_ More fact about Tsushima Shuji is he had a part of "Book" in his soul which means that he is the special mixed products of Dazai Osamu souls and the "Book". Tsushima Shuji is the last backup plan of the "Book", yes, it has consciousness like a human.

_ When the unknown Cthulhu god approach to Tsushima Shuji world, they almost woke up the sleeping Cthulhu god who created the world of Tsushima Shuji with his dream. And at the very moment that god was about to awaken, the "Book" awakened its will. In order to save its own fragile false world about to be destroyed, it used almost all of its own energy to create a shield around Tsushima Shuji's world so that the unknown Cthulhu god could not enter and also let the dream god Cthulhu once again fall into a deep sleep.

_ As a result, the "Book" began to weaken, it could no longer exist in the physical state.  The "Book" represents the world, if the "Book" pillar weakens, the world will be next to broken even if the dream god Cthulhu created Tsushima's world never awakened.  The shield that envelops the world is only a temporary measure to slow down the time when the world is destroyed.  The fact that the "Book" uses almost all of its survival energy also affects the birth of predetermined characters in the Bungo Stray Dogs universe. The "Book" only has enough power to create the souls of 5 key characters, namely Tsushima Shuji (Dazai Osamu), Nakahara Chuuya, Izumi Kyouka, Akugatawa Ryunosuke and Nakajima Atsushi.

_ The fact that a world in the Bungo Stray Dog universe has almost all the characters appearing in the main and secondary plot shows the healthy and stable state of that world, on the contrary, that world is too weak, like a torn piece of paper about to be torn by the wind which is the situation of Tsushima Shuji world now.

_ So, the "Book" decided to merge with Tsushima Shuji soul to increase his soul rank and ability rank as a backup when the world is destroyed, Tsushima Shuji has the ability to carry the remaining 4 people to a safer place. After doing his duty, the "Book" sleeps in Tsushima Shuji's soul, only to awaken when he is in danger.  In the process of fleeing from the Tsushima clan, Tsushima Shuji's special ability also awakened. His ability is non - named.

_ Unlike most Dazai Osamu passive "No Longer Human" special ability, Tsushima Shuji can automatically open and close his powers.  Furthermore, if the majority of Dazai Osamu's abilities have one thing in common, which is nullify most of the "ranks" of abilities, then Tsushima has another function in addition to that function.

_ Tsushima Shuji's singularity has a unique tendency regarding the preservation of souls while traversing space and time.  He has the ability to temporarily absorb other people's powers. Upon physical contact, Tsushima Shuji is able to absorb and use the other creature's powers, and neutralize their heterosexual abilities.  This power can be especially useful in situations where Tsushima Shuji needs a specific strength to overcome the dangerous challenges of traveling through different worlds.  However, Tsushima Shuji must always be very careful when using this power as it will affect his mental and emotional state because Tsushima Shuji will temporarily have human or absorbed object.  The use of powers has the potential to cause him to lose his sense of self, and Tsushima Shuji always needs to be careful not to get lost in the memories of the possessor of that ability he absorbed.

_ As well as the difference in abilities, Tsushima Shuji's personality is also surprisingly kind compared to the other Dazai Osamu which is shown in the fact that he cherished life since he was a child even though no one taught him about it (maybe it's because of the influence of the "Book" will to save the world in his soul).  There is an interesting thing about Tsushima's personality is that he is a stubborn person, no one can stop him whatever he wants to do with all cost, Tsushima Shuji is also a tough guy, this trait can also evident during the defection to Yokohama.  If Tsushima Shuji's will hadn't been strong, he wouldn't have escaped from the Tsushima clan's sacrifice.  There are many times in the process of using the "Book" to escape, because having just awakened in the period of weakness, the ability to conceal and rewrite the destiny of the "Book" has many limitations, when works when it doesn't. Tsushima Shuji had to use all his wisdom in the body of a 3-year-old child to avoid the illusions and traps that the Tsushima clan's Cthulhu god fanatics set up.
