Kazuma was Fenrir all along. The tattoo possessed him three years ago, and sealing it with Cat-sìth was the only way to keep it in check. But the shock of Eiji’s death weakened the seal. And now that it is broken, Fenrir reveals another shocking truth...
But he wasn't concealing Fenrir.
.لكنه لم يكن يخفي فنرير
Aber er hat Fenrir
nicht vor uns verheimlicht.
Sin embargo, 
no estaba ocultando a Fenrir.
Mais il ne dissimulait pas Fenrir.
Ma non stava nascondendo Fenrir.
Однако он вовсе не скрывал Фенрира.
