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.
Could there be a more pointless 
way to use a skill?
هل هناك سبب أتفه من هذا لاستخدام مهارة؟
Wie kann man einen Skill so verschwenden?
Sérieux,
c’est du gâchis de compétence.
Ma perché usi in questo modo assurdo le tua abilità?
Que desperdício de habilidade é esse?
Ну и дела…
нашла на что навык использовать.
