## Guide

**"Undo the Cipher and Tighten it's Cords"** (解 (と) いて暗号 (あ ん ご う) の緒 (お) を締 (し) めよ, *Toite Angō no o o Shimeyo*?) is the 4th chapter overall and the 4th chapter of the 1st volume of the *Cipher Academy* manga, written by Nisio Isin and illustrated by Yuji Iwasaki.

## Summary

The chapter begins with a confrontation between Yukako Omomuro and Iroha Irohazaka, with Tayu Yugata as a spectator. Iroha is seated on the ground, visibly nervous as he examines a code and realizes that something is amiss with his glasses, his cryptographic tool. He carefully places his glasses down, and Yukako inquires if he is admitting defeat. In response, Iroha simply states that he is leaving his glasses behind to prevent them from getting damaged in case he cannot decipher the code. Additionally, he asks for a hint, to which Tayu provides a cryptic clue: "There are as many hints as there are stars."

Iroha departs for the library to research the code, while Yukako and Tayu discuss their puzzlement over Iroha's non-violent approach. In the library, Iroha initially interprets the code as representing the United States, associating it with the word "stars." Consequently, he begins researching all the states in the U.S. Iroha soon realizes that the code Yukako provided follows a similar rule to the one Kyora Toshusai gave him a few days earlier. While working on it, he acknowledges that deciphering codes is a demanding task but finds it genuinely intriguing, especially when tackled through hard work rather than shortcuts.

The narrative jumps ahead three hours, as Iroha presents his decoded message to Yukako. Although Iroha successfully solves the code, he has exceeded the time limit. Iroha nonchalantly remarks, "I suppose it's a tie then, right?" Yukako is visibly dismayed by this outcome. Iroha explains that despite going beyond the time limit, he managed to decipher the code, resulting in a draw. Tayu bursts into laughter in the background, provoking Yukako's angry outburst.

With the match ending in a draw between Iroha and Yukako, Iroha inquires if he needs to face Tayu next, to which she responds with disdain for picking on weaker opponents. Towards the end of the chapter, Kogoe Horagatoge arrives with the charger for Iroha's glasses and remarks that Iroha didn't actually require the charger in the first place. Kogoe and CG discuss how a draw turned out to be the best outcome for Iroha. They also note that Iroha must have recognized that the primary purpose of his glasses weapon is to develop the user into a more adept cipher soldier. As the chapter concludes, Iroha becomes aware of something unusual about the solution to the code that Yukako had presented to him.

**"Tight Lipped When Questioned, Capable of Destroying Castles When Speaking Freely"** (問 (と) うに落 (お) ちず語 (かた) るに落 (らく) 城 (じょう) , *Tou ni Ochizu Kataru ni Rakujō*?) is the 50th chapter overall of the *Cipher Academy* manga, written by Nisio Isin and illustrated by Yuji Iwasaki.

## Summary

The Chapter starts with Iroha Irohazaka sitting in an interrogation room in front of Iiai-chan and Akuai-chan. Iroha explains his journey from B44 and how they all escaped from the Mahjong floor and met up with Oboro. Akuai-chan explains that Ensa Kasuri and Soboro Oboro are experiencing the same situation in separate interrogation rooms. Iiai-chan also adds that they have the right to stay silent, but also the right to betray their allies.

If 3 people betray, everyone will receive a sentence of 24 hours. If 2 people betray, those who betray do not receive a sentence and those who remain silent receive sentences of 36 hours. If 1 person betrays, the one who betrays doesn't receive a sentence and gets to skip ahead 120 floors, while those who remain silent receive sentences of 48 hours. If no one betrays everyone receives sentences of 12 hours.

This scenario is something that Instructor Kumomakka Kumorigumo went over with them. On B180, Quokka and Tonbo discuss when they encountered on B100. They reveal that they were able to unify their minds thanks to the help of their instructor. Iiai-chan also tells them that once they are in custody, they are unable to remove their glasses weapon, meaning that they can't just escape by taking it off and logging out.

In the real world, Seppun states that no cipher soldier would betray the other cipher soldiers, even for the sake of a dream, in which Kogoe replies with the fact that they might not betray for a dream, but instead for the sake of reality. It is then revealed that Oboro is indeed an ex P.O.W. and an escaped convict who is currently a fugitive. Like Oboro, Sunka information was kind of similar, she plans to use the Morgue to pay off bails and penalties. Iroha and Ensa realize that for people like Oboro and Sunka, the labyrinth must be completed.

In the end, Oboro confessed. She confessed that she did the crime all on her own, allowing Ensa and Iroha to go on and skip 60 floors each. Oboro ended up with a sentence of 72 hours. Iroha and Ensa moved down to B160, the department store floor. The chapter ends with a scene showing Sunka, Oboro, Ensa and Iroha, all progressing onwards.
