Saara dies in most possible outcomes by this point before 20

Valentino canonically dies before 25, though i like to keep possibilities open

Oshiru suffers from his bodyweight already and the fact he's still growing and gaining mass he'll most likely die from that sometime before or around mid-age, or is otherwise hospitalized 

Junius suffers from heart-conditions so yeah he'll die probably mid-school if he's forced to do something that requires lots of running around

Mana is a lil shit who'll carry his own feelings to the grave, most likely living a long lonely life while cursing how he exists but still doesn't
