An entity mentioned in the final volume of the Blue Archive.
An existence called the leader of color that appeared in the final part of the Blue Archive. Enshrined in the deepest part of the OOPARTS "Atra Hashith's Ark", it features an eerie appearance that looks like a hand covered in bandages is pulled out of a coffin. I have a Shittem box with a cracked screen that says "Jericho's Lament" and "Seven Old Rules", which are different from the passwords that the teacher entered, "Seven Lamentations" and "Jericho's Old Rules". .
