I figured it out,
Darkness-chan is just a Tsundere and Yandere..
Their a fleet of pyramids... a harem.
And Traveler Senpai is the Anime Protagonist who like Tenchi has tried time and again to run away..but to no avail!
"I could tell you" of the Darkness which has "pursued" the Traveler, "But I won't."
