Leon farming aura like it's nothing. One scene was skipped: all crimson flame dragons around jumping over Leon's body forming a cage of bodies while spitting flames on him inside. The chidori roars (as in the Naruto's chidori just way bigger), Noah and other dragon maids watching from the castle windows in horror, Noa wonders how his gentle dad who is always at the mercy of her mom can be that grinding machine shredding dragons his way in the battlefield. Leon's bolts of thunder slicing every dragon around like a living grinding machine, dragon body parts and blood splattering around while Leon keeps advancing towards a shocked Constantine and Anna under his feet. Well other than that is well adapted so far even the text is 1:1 from the novel in many parts.
