No Alcohol Until You Turn 20 (お酒はハタチになってから) is the 15th chapter of the 2nd volume and the 42nd chapter overall of the Spoof on Titan manga, written and illustrated by hounori.

Overview
Gelgar's alcoholism places everyone's drinking in the spotlight.

Summary
In the mess hall, Lynne complains that Gelgar has entered the incorrect data once again. Nanaba remarks that he has not been focusing on work as of late and suggests that she and Lynne remind him to be more cautious.

Approaching Gelgar, the two women are surprised to find him drinking on the job and reprimand him for his behavior. Nanaba confiscates the bottle of alcohol but Gelgar assures that it is merely water. Nanaba is unconvinced and calls him a liar, but later proves herself wrong as she inspects the liquid and confirms that it is indeed water.

With the bottle confiscated, Gelgar dejectedly reveals that he thought he could distract himself from alcohol by only pretending to drink, but this abstinence backfired as he felt less concentrated on work. He also reveals that his doctor made him quit, else his illness grow past recovery, but he gets a smacking from Nanaba after telling her and Lynne that his illness is a bad case of penury rather than something physical.

Suddenly, Mike interrupts their conversation and invites Gelgar to drink under his tab. Lynne and Nanaba ask to join in, while Levi and Erwin tag along and accept Mike's offer despite not being invited in the first place.

Anka rewards Pixis with a bottle of alcohol for finishing paperwork, but the bottle appears to be nearly empty as Anka comments that he will only be rewarded based on his daily efforts. Eager for more liquor, Pixis orders her to bring him more paperwork once he finishes his glass.

Hugo offers Hannes alcohol but Hannes refuses as a vow to cut back on his intake after failing to save Carla Yeager from a Titan while under the influence. Later in the day, Eren asks Hannes if he has been drinking, to which he sheepishly admits.

In the Training Corps' mess hall, Connie wonders who among the trainees would pair best with liquor. Armin suggests Reiner while Jean suggests himself. More suggestions surface until Marco offers the boys milk.

Conversing with Nanaba, Lynne comments that Gelgar is drunk again. She tells Gelgar to work but to no avail due to a hangover he got from drinking too much the night before. Gelgar excuses himself to drink water in hopes of relieving the hangover, but Mike correctly suspects that it is alcohol and reminds him to not drink at work.
