第5話: GilgameshがRitsukaとMashを水質検査のため海岸の観測所へ護衛する。
Gilgamesh personally assigns Ritsuka and Mash to be his escorts while he travels to an observatory on the coast in order to inspect the water quality of the sea. Along the way, Ritsuka and Mash tell Gilgamesh stories about their adventures in the other Singularities. While Gilgamesh claims their stories don't interest him, he does acknowledge that they have been on a great journey. After reaching the observatory and collecting the water samples, Ritsuka and Mash take a break on the beach while Gilgamesh handles other matters. Mash continues to wonder if she is truly human or not, while Ritsuka reassures her. Suddenly, they are attacked by Enkidu, and are only saved by Gilgamesh's intervention. Despite claiming to be an impostor, Enkidu cannot bring himself to kill Gilgamesh and retreats. As Ritsuka, Mash, and Gilgamesh return to Uruk, Enkidu tries to convince himself that he is merely an impostor of the real Enkidu and that he should have no issue killing Gilgamesh.
