If you use Shadow Movement to sneak into houses and a pegasus team to pull the flying sleigh... yes, in this world, it's possible to become Santa Claus! But... the Christmas tradition doesn't even exist in this world. When Rimuru tries to explain it in detail to the people of Tempest, they end up summarizing it as a "party." The Christmas cake and presents are ready, and most importantly, Kaijin and the other Dwarves create gorgeous decorations that bring the Christmas mood to Tempest. On top of that, Eren and the children treat everyone in town with their heavenly singing.
And make smiles bloom
ونجعل البسمات تتفتّح
unsere Gesichter ein Lächeln zieren.
Otorga sonrisas
Otorga sonrisas
Afin que s’épanouissent les sourires
facciamo nascere dei sorrisi sui volti
Pra ver o sorriso florir
Пусть расцветут на лицах улыбки!
