I reminded you that now the MC (Oranai) no longer has any memory's of his precious world nor of his speeches with Rob and his memories are the same as itachi although this has been changed to adapt to his powers.
POV OBANAI
Obanai * Okay so I'm in a different world.
I don't know how it's done my all my senses tell me it's not a genjutsu
My illness also looks better as if it had never been there *
looking around he realizes that he is in a forest
Obanai "Very well its going to help me so I will be able to train but combat technique and power"
then looking at it is power more closely he discovered something interesting
Obanai "Firstly my Infinity is to strengthen and secondly I no longer lose sight with my occular powers however my susano always does serious damage to the body after its use"
After having analyzed in more detail the advantages and disadvantages of his powers in his world he decides to learn about the world in himself because it could be dangerous to walk around without knowing anything about the world.
for two weeks he stayed in the forest to train and get used to the power of his body i mean he was a normal person before so you have to get used to using them even if you have them and at the end of the second week he decided to move to get to know his world better
Since entering his world Obanai has discovered several things
Obanai "Magic is common here and my powers are considered magical which I think is useful I wouldn't want to attract powerful people just because I use different energy"
while he was walking in magnolia he was attracted by a great magical concentration
Obanai "if I'm not mistaken its should be pre fairy tail I should go see it could be interesting *
as he approached the members of the Fairy tail guild despite their fears of the Jupiter cannon they turned their eyes to Obanai who unleashed all his power
Erza "he is ... he is .... he is stronger than the master"
Obanai "Sate Sate Sate didn't look so dangerous to me"
After he finished speaking his he Activated his Susano to counter the Jupiter cannon
The moment the Susano was activated it seemed as if all the surrounding mana was focused on Obanai to such an extent that even the Jupiter Cannon was no longer supplied with magic if the mages present had to comment on what they saw there. would have one word on their mind Terrifying
Erza "is he ... is he human are power .... he looks like a ... no he's a monster"
Everyone present could only nod to show their agreement
however he was wrong, it was only the beginning
After stopping the Jupiter cannon without even moving an inch everyone could hear his voice
Obanai "Amaterasu"
then a black flame was thrown on the phantom lord Don guild the shrill sound and voracity frightened the two Guilds
