Wish Upon the Pleiades

Nanako 13 (1x8)

Air date: May 27, 2015

A part of the engine appears 0.25 light-years from Earth in the furthest corner of the solar system. It would take three months to get there at the speed of light, and to top it all off, someone would have to go ahead and pinpoint the location. The one who volunteers for this lonely trip is Nanako.
