Twenty-Fifth Baam (스물다섯번째 밤, Seumooldahseotbeonjjae Bahm; "Twenty-Fifth Night") or simply Baam for short, is an Irregular and one of the main protagonists of Tower of God. Baam entered the Tower in search of his best friend Rachel, another Irregular, and after passing Headon's test he was deemed worthy of climbing the Tower. After later being forcibly recruited into FUG, Baam joined Team Tangsooyook and managed to escape from FUG's clutches, eventually reuniting with his old friends and teammates. Due to his affiliations with FUG, he also goes by the name Jyu Viole Grace (쥬 비올레 그레이스, Jyu Biolle Geuleiseu).
In Korean, the word "baam" has two meanings: one is "night" and the other "chestnut." The latter meaning is highlighted by Headon, who abbreviates his name to Baam, joking, "It has become a tasty name!", and the Second Floor Guardian who tells Baam, "You... look tasty".
He goes under the alias Jyu Viole Grace in Season 2. It is speculated that he might have been adopted by the leader of FUG, Grace Mirchea Luslec, but this has yet to be confirmed. When he meets Garam Zahard on the 43rd Floor, she tells him that his name comes from his parents -- "Grace" from Grace Arlen and "Viole" is probably from V.
It has been stated in a blog post by SIU that the origin of the name "Viole" is the colour violet. Coincidentally, "Viole" is an old French word used to describe a European bowed stringed instrument used in the Medieval period.
Because of his status as a Slayer Candidate, Baam has financial backup from FUG up to the point where it can surprise many Rankers. It has been exemplified by Ha Jinsung buying Lo Po Bia Elaine for an unthinkable sum even for Great families' financiers.
He is apparently a great cook, having to cook for himself and Yeon, with Wangnan even calling him a super chef. His best dish is cream spaghetti, which happens to be a dish Androssi ordered before the Submerged Fish Test.
Surprisingly, Viole's clothes are all picked by Ha Jinsung. He is troubled by the fact that Jinsung sends him clothes every season.
According to Hwa Ryun, it is thanks to Ha Jinsung that FUG gives some freedom to Baam.
After the 28th Floor test, Viole buys junk food items for Team Tangsooyook. However, he has to eat them in secret or else Goseng will confiscate them since they're unhealthy. As a result, Viole has become a "black market" supplier and is very much loved by Miseng and Prince.
He is ambidextrous, but was taught to use his right hand more.
SIU stated that both he and Rachel know many secrets about the Outside.
He is the once-dead son of Grace Arlen and V, who was later brought back to life by an "Outside God". This was revealed by Garam Zahard on the 43rd floor using Arlen's pocket as evidence, a fact confirmed later by one of the 10 leaders, Poe Bidau Gustang.
Among his core team (Himself, Koon Aguero Agnis, and Rak Wraithraiser), he was only shown with the shape of his shinsoo when using the clickers. The others were shown the quality and shape.
(To Ship Leesoo) "My name is Twenty-Fifth Baam. For short you can just call me Baam. Even if you tell me to introduce myself, there's not much to say. I don't have parents... or a home... a single set of dirty clothes is all I have. I always thought that I might die alone without ever being able to do anything... But now- I have friends. Thank you."
(Response when put in a danger of death situation) "There is something I fear more than death."
(To Yu Han Sung) "If Rachel isn't up there, that place is nothing more than a pile of garbage. No matter what's up there, that won't change. You told me that being like I am is strange, but to me, you're a person who can't even find a single thing that's precious within that huge pile of garbage."
(To Androssi Zahard) "If I must fight, I will fight to protect what is precious to me."
(To Hwa Ryun) "What's this rising emotion from my heart... I'm not sure... I have to find out...! Why... Rachel... betrayed... ME...!!"
(Denying the requirement of team members on the 20th Floor) "I am Jue Viole Grace, one of the Slayer candidates of FUG. Zahard and their kin... I live for their death. That is why none of you can become my teammate. I am your enemy."
(To Yeon Yihwa) "There is no way that everyone can be happy. It's only possible that someone will be happy."
(To Urek Mazino during the Flower of Zygaena Test) "Stars, thrones, skies, the outside world, I don't need any of those things... But if someone tries to hurt those that are precious to me, I will fight."
(To Novick) "Even if I end up broken, if I can protect everyone else, I will do it. If I can do that, it doesn't matter if I break one day. Besides, I lost my reason to live a while ago."
(To Xia Xia) "I'll go with you. But if you try playing with my friends' lives like this again... I will kill all of you."
(To the false Followers) "What is the meaning of this? I will win with my own power. Don't just make me your god at your own whim. I am not some kind of convenient machine that makes your wishes come true. Now am I still your god since I am no longer a convenient tool to you?"
(Thinking to himself while watching the other Regulars fight) "They're all fighting for something. They all pray for a certain wish, they fight, they battle and they desperately gather. If so, why have I come here? What do I want? What did I come here for? Rachel... where are you now?"
