Final Eight Arc
Grandpa Someya makes his first appearance in a flahback of Mako's. Here he is sick in bed and talks with Mako before noticing that she has poor eyesight. He then gives her a pair of his glasses and says it isn't time for him to give up yet, before pulling out another pair of glasses. It was earlier noted that Mako grew up around her grandpa and that he practically raised her.
