Sup /mono/ hear me out on this:I was thinking up a few theories to Monoko's death. This one being that Monoe (older sister) was running and Monoko (little sister) was trying to catch her, and even though there was a red light, Monoko ran across the street and got hit by a car, dislocating her left arm, breaking the right one, having her internal organs cut up and there being a large head wound (from impact). And the arms appear from the wounds she got as she died from the accident. Monoe, in complete shock at witnessing the death of her sister, ran into the dark forest. Monoe never went home and spent the rest of her life constantly running away from anyone who tried to look for her because she felt guilty for the death of Monoko. Eventually she drowned herself in a river, when her body was found, it had a smile on it's face, perhaps because she finally found her baby sister.
...I think this really belongs on /t/, but a decent theory nonetheless.
Monoko and Monoe may be the same person - before and after the accident.
