Ragnarök () is the 223rd chapter of Yoshifumi Tozuka's Undead Unluck.
Summary[]
Fuuko is left shocked by the next Quest already being available, with Andy theorizing the cause must be one of the Superior Rules, the seventh seat, "Time", speeding things up to prevent Unjustice's awakening. As a blindsided Fuuko mutters about the lack of time, Apocalypse suddenly announcing one month passing, activating the the penalty Ragnarök. On the moon, Soul confronts Luna over preventing the Rules from acting on their own before trying to attack her. Luna responds that because they were detained by Undead, she "asks" Soul to return to being part of him as she suddenly enlargers herself and grabs him, stating it would be "more amusing". Back at the Roundtable, Nico alerts Fuuko that the Superior Rules that landed on Earth have started to ascend again back to the encroaching Sun. Luna then states the Union must overcome Sun "at their best", who has merged with all ten of the Master Rules, to show her "the true value of the rules".
As Fuuko panics, Andy tickles her to have her calm down. He then states that its Sun and the Rules are panicking, the reasoning being the fact they are acting like this. After once more recallng Juiz's Unjustice and Fuuko's efforts in forming the current, and final, Union, the Negators exit the Union base to engage in a final battle against Sun for the fate of the planet.
