#“you will be my witness” - that night mori signed dazai's name on a contract dazai had no clue he had even drawn

[ninkaku]

i could talk all day about mori's treatment of dazai and the way he abused his power over him but i'd rather talk about the ways in which he is still doing it, despite dazai having left the mafia. as we know, dazai left the mafia under oda's instruction, a promise he made to his dying friend in which he said he would become a good person, and be on the side that saves people. oda said, the sides make no difference to you, so he knows for a fact that dazai has no reason to do these things, when good and evil are mere concepts for him and not something he feels drawn to either way. a take i've seen often and one that i quite like is not only did mori have oda killed for the mafia's own personal gain (the deal struck so that they could operate under legal means), but it falls back on mori grooming dazai to one day take his seat. up until this point, dazai has never had anything worth protecting, has never lost anything, has never grieved anything and never experienced the emotional call to despair.

odasaku's death and thus dazai's push into the light, which ends up being with the ada, is the final piece that mori needed to solidify that dazai would one day be able to take his place. they talk about it, dazai says you were afraid of me, weren't you? and in more ways than one, the statement is true. mori had always known that he would and always wanted for dazai to surpass him, but the husk that dazai had become by never wanting anything, never protecting anything scared him if dazai was to dispose of him and assume his seat, because although dazai is a genius, he was callous and didn't value anything. he wouldn't value the mafia like mori does, he wouldn't protect yokohama like mori does. during the guild arc, mori says if dazai was still my right-hand man, the guild would stand no chance. dazai inside of the mafia and outside of it exists as a powerful adversary to whomever he stands against, and i think this is one of many reasons why the ada and the port mafia exist somewhat in tandem. the port mafia and the ada overstep their boundaries from time to time with each other, but the truth lies in mori knowing that dazai could ruin them if he intended to.

in something of a tldr mori aims to push dazai out of the mafia just as much as he intends to keep him within it. he needs dazai to experience loss, needs him to experience what it feels like to protect something, what it feels like to want to protect something. the fact that after dazai left, mori has not replaced his seat as an executive. has not replaced dazai as his right-hand with someone else, continuously offers him his position back means he fully intends to have him back under his wing again, someday. means he fully expects, once dazai has experienced what he needs him to, that he will take over his position, and he will drive dazai back to him. yosano and dazai serve as two prizes that mori currently does not have on his mantle, and in the deal struck with the president of the agency, those are the two he is most likely to pluck out of their ranks to put right back into his own.
