But well, we still don't officially know who this Kuroiwa-kantoku is or what is he really intending to do with Shinsei Inazuma Japan. But since he was seen talking to Endou (Mamoru, I assume? Haha before reading the wiki I thought it was Endou Daisuke) in the end of the first episode, I think he got good intents, as it's impossible for Endou to "sabotage" soccer, unless Kuroiwa is pretending once more. From the past Season 3, we all know before his so called 'death', he became a good hearted person in the end, especially showing care for Rushe.
