Akio, You Will Live On in Our Hearts / Goodbye, Grandpa

This episode involves the tragic moment in life that is death. In the first half, Reiko-chan must cope with the death of Akio, a weird, 4-legged, 3-eyed, severely malfunctioning robot she loved so much, with her still functioning partner, the centauroid Mamoru, which, of course, also suffers from strange malfunctions and mishaps. On the second half, the grandfather of a family, with his time running out, recalls the memories he had with his old friends - only to encounter severe and weird anomalies.
