Question About Yami (Spoiler)

[Nach4n]

I finished the game but cant seem to figure out the connection between the boy and Yami. Are they brothers? (When you play as Mom, In her House, You'll notice two single futon, One Double Futon, which indicates double futon is for mom and dad, the other two single futon, one for the boy and i cant figure out whom its for)

Also, About Tonys Son, How Did He Die? in Morizora he falls down in the river, i am thinking in real life, he got into some kind of accident while playing hide and seek in the house.

Last Question, What actually happens to the boy? why was he sick? and if you notice uma was in the ship to Rakuen.

It seemed the boy and Yami were the same person, though Yami was the boy's inner darkness or pessimistic imagination keeping him company during the loneliness. The boy like anyone would've experienced at least some anxiety, anger and/or cynicism with everything that's gone on. There were signs throughout the game the boy had a surviving brother although this wasn't really confirmed until we see him in the credits and Laura/supershigi on the forums here posted about this somewhere. I didn't see anything that ties the brother and Yami either and "Yami" is an usual name for someone as it mean "darkness". IIRC Yami was introduced like a stranger too....either that or it was because the boy was suffering from some cognitive dysfunction as a result of the medication and/or the illness.

I believe Tony's son died the same way - he played around on a bridge that collapsed into a river. His daughter however for some time experienced severe guilt being present and unable to stop or save Benny (IIRC), and thought Tony was punishing her by avoiding her even though it was because he was mourning and seeing her reminded him of Benny.

There was a clue in the boy's notes south of his bed - the medication is primarily used for lung cancer. It was also revealed by the end that the boy was bald which is a common side-affect for treatments like chemotherapy, for cancer. It's unclear how the boy got cancer (not unusual for real life), but I don't think it was from the Fukushima disaster as it seemed he got sick before the tsunami hit....and falling ill so fast from sub-acute exposure doesn't happen with nuclear/atomic radiation.

Uma was seen on the ship indicating he had also died although it's unclear to how and when. Since he was elderly and apparently left his family and lived on the streets/in poverty he most likely would die from exposure or poor health, or possibly the result of the earthquake/tsunami.
