— Chlammy, Rule Number 10
Chlammy Zell (クラミー・ツェル, Kuramī Tseru) is a human who allied herself with the Elves to try and win the king's contest, due to her belief that humans will never be strong enough and must depend on others to survive. She is the friend of the Elven girl Fiel Nirvalen, despite being a slave of Fiel's family.
After Sora bet the Race Piece of Immanity in their game with the Eastern Union, Chlammy Zell challenged Sora in an attempt to win the Race Piece. However, Sora, as he was challenged and thus had the right to choose the game, chose a game in which they would both bet everything they have in parts, tricked her into sharing his memories with her in a game of Othello. After Sora won the game, he returned all memories to the respective owners. After Chlammy had seen Sora's memories, she decided to go along with him and his plan.
She is a descendant of Nonna Zell, one of the surviving Immanity of the Great War. It can be assumed that somewhere between the last 6000 years, her family lost a game to the Nirvalen family, thus becoming slaves up-to present-day Disboard.
Chlammy Zell is a short girl with purple hair, and most of the time wears a black veil draped over her head.
She holds a non-emotional expression before her defeat by Sora and Shiro. When Sora yelled at her for underestimating the human race, she threw away her confident facade and broke down in tears while childishly calling Sora names and blaming him. When she did a rematch with Sora, she still acted pessimistic about the possibilities of the Immanity. After being defeated again and having her memories restored, she gained a newly found respect for Sora and the Immanity. They parted ways on good terms as she agreed to help defeat the Werebeasts and unite the other races. She seems to have a slight breast size complex, as revealed in Episode 10. While initially finding Sora as a cocky, all-around lazy, and hurtful person, she changed her thinking upon seeing his memories. In Episode 12, she admired how Sora managed to accomplish all his goals without spilling a single drop of blood, flying without wings, and staying himself despite all the odds.
She coordinates well with her friend, Fiel, allowing her to sneak elf magic into games intricately enough that it can be hard to detect the source, even for those capable of sensing magic (as in the case in Volume 5 Prologue against Barter).
She also had the initiative to take the crown and helping Immanity to stand before Sora and Shiro came to Disboard. She was able to think through how the Elves were able to protect Immanity from the different races and attempted to take the crown from the gambling competition.
She greatly underestimated Immanity, thus also underestimating her abilities. Since her encounter with Sora, however, she learned to have more faith in the wisdom of humanity, although she may still believe Immanity is at a disadvantage to the other races, she learned that Immanity can cope with it through other methods and has since been studying ways to overcome Elven magic, despite Immanity being unable to even detect it much less use it.
