Enjoy! Field Trip (満喫!りんかいがっこう Mankitsu! Rin kai gakkō) is the ninth episode of Isekai Quartet. It was first broadcasted on June 4, 2019.


The male members of the Imperial 203rd Aerial Mage Battalion can't help but feel like they're in Valhalla, after seeing the beautiful girls in bikinis. Before they can enjoy themselves, however, Cocytus orders them to do a thousand push-ups. Darkness also joins in doing the exercise, her actions prompting the soldiers to stop while admiring her chest. Ram and Viktoriya, who are watching nearby, call them scumbags. Subaru greets the two ladies while asking how the BBQ is coming along, Ram notes that Subaru is being lazy.

The three hear a scream from Kazuma, who is in pain due to Demiurge using [Flash] to temporarily blind him when he was about to use his stealth skill to peep at the girls. Tanya scolds him for disrupting the peace as a member of the Disciplinary Committee, which she considers disgraceful.

Rem and Shalltear Bloodfallen are seen together underneath a tent. The trip begins to pick up, with the BBQ, Watermelon Splitting, etc. After the sun sets, Roswaal begins the Test of Courage and groups are assigned and go through the forest. The first group is composed of Vooren Grantz, Megumin, Beatrice, and Mare Bello Fiore. The second group is composed of Matheus Johan Weiss, Viktoriya Ivanovna Serebryakov, Shalltear, and Aura Bella Fiora. The third group is composed of Demiurge, Kazuma, Ram, and Albedo. with Albedo claiming that it wasn't scary at all.

The fourth and last group contains Subaru, Tanya, Ainz Ooal Gown, and Aqua. The goddess asks if the remaining three are from Earth. The other three are surprised that she knows, with Aqua explaining that she can tell because she sent Kazuma to another world. Tanya, learning that Aqua is a deity, becomes tense and lashes out at Aqua, believing that she is Being X as she discharges her magic around her. Ainz attempts to calm her down, but this falls deaf to Tanya's ears as she approaches Aqua. Aqua, scared and confused, tries to reason with Tanya, but the military girl ignores her. Subaru puts himself between them. Tanya only relents when Ainz tells her to think logically as to how could Aqua be Being X as she was also sent here to the current world. Tanya, seeing the terrified Aqua, realizes they are not the same being.

Tanya apologizes to Aqua, stating she took her words as a god too seriously, though Aqua corrects her that she really is a goddess. The others soak that bit in and realize Aqua has been claiming to be a deity, but they never took it seriously. The group meets with the others, who ask if everything was alright, as they witnessed the electrical storm caused by Tanya. Tanya explains that she lost her cool and apologizes.
