Record of Ragnarok, Vol. 18

Humanity's greatest heroes battle the gods for the survival of the human race!

Until now, humanity's champions have been heroes who fought with great skill, cunning, and magic. But with Nikola Tesla in the arena, they now have a hero who fights with the power of science! In life, Tesla unlocked many secrets of the universe, including the ability to control gravity. But can this miraculous power stand up to Beelzebub wielding a technique that is forbidden even in the depths of Helheim?
