Akechi’s life

so there’s something i think i’ve missed about akechi’s story

was his mother a random girl raped by shido or they were actually kind of togheter and he raped her?

did shido know she was pregnant of him?

did Akechi know her or she died right after having him?

when akechi showed up to shido to cooperate with the murders, did shido know he was his child?

how did akechi know about shido being his father?

where does akechi live/sleep when the game occurs?

where did akechi live his childhood?

sorry about the questions i’m just curious.

edit: and this is random but i just thought about this. do we know who Futaba’s father is? does she canonically know?
