Volume 1

The 1st volume of the manga contains 15 chapters and 5 extras.

Outer Cover
The main trio are at the riverbank. Hidenori is seated with a book in hand, Yoshitake is standing and eating a snack, and Tadakuni is pointing towards the river. A little distance away stands the Literary Girl, staring at the river. The flap shows an extension of the bank. Four boys are gathered at some distance behind the main trio, among whom are Karasawa and Motoharu. Karasawa, who is seated, offers Motoharu some snacks.

Feature Spread
The spread is titled ‘Prefectural Sanada North High: 2-A Class Picture’. It features two rows of students wearing all kinds of outlandish costumes, detailed below:

Front Row (L-R)

 * Karasawa – Wearing cat ears on his cap and gloves styled as cat paws.
 * Megane – Wearing a maid outfit.
 * Motoharu – Wearing a cape, a diadem, and carrying a broadsword.
 * Chapatsu – Wearing a girl's seifuku.
 * Unnamed – Wearing a full-length teddy bear outfit.
 * Unnamed – Wearing an eyepatch and a black glove. One sleeve is torn halfway and the corresponding arm is bandaged like a mummy’s.
 * Unnamed – Wearing pants with a giant dark splotch between the legs.
 * Mitsuo – Kneeling on his chair.

Back Row (L-R)

 * Unnamed – Wearing shorts and only the top half of the school uniform’s top, with a mini-tie to match.
 * Yoshitake – Wearing no clothes whatsoever, except a long tie covering his privates.
 * Unnamed – Made to look like blood is spilled all over his uniform from a nosebleed.
 * Unnamed – Strongly resembles Hidenori but for his hair. Wears a shirt reading ‘shota moe’ (ショタ萌え).
 * Unnamed – Sporting Saiyan-themed shoulder pads and spiked hair, like Vegeta.
 * Hidenori – Wearing a wig and a cartoonishly long mask that makes his forehead and chin look abnormally large.
 * Unnamed – Wearing white face paint with a dark design on it.
 * Unnamed – Wearing his school coat but no shirt. The coat flies behind him like a cape and clothes pegs are attached to either nipple.
 * Tadakuni – Wearing a black afro and bushy chest-hair.
 * Unnamed – Wearing a wig styled like a girl’s long hair, with a bow to match.

A makeshift sign behind the boys reads "You are saved, but the Earth is doomed!" (unsure of the translation).
