The world's strongest exorcist is a master of Japanese magic who is betrayed by his country and killed because of his power. He reincarnates in a fantasy world where he has no magical power at all, but...
and became the strongest 
in every sense of the word.
.وأصبح الأقوى بكل ما تعنيه الكلمة من معنى
Ich wurde der absolut Stärkste.
y me hice el más poderoso de todos.
y me convertí
en el más poderoso de todos.
Personne ne rivalisait avec moi.
e sono diventato
 il più forte in assoluto.
e me tornei o homem mais poderoso.
стал самым сильным.
