Onion

Onion was a Japanese orphan during the Hiroshima bombing, he was a member of Ryuta's Gang, and was always seen alongside his fellow members. Later, when the gang goes hungry they all decide to steal potatoes from a farmer nearby, however Onion is singled out and beaten on the head with a wooden baton by the farmer, likely suffering severe brain damage he is taken back to the hideout and he wishes for a pickled yam, but since food was scarce Ryuta could not find one in time, and Onion died of his wounds.
