After diablo finished fighting with Alex, he say that alex was fun but he got bored to an extent. A purple beam then flies out of nowhere and hits diablo causing an explosion ,kazuki(with his spiritual mark activated) says that there is no way anyone could have not get critical damage from a direct attack like that. Diablo walks out of the smoke caused by the explosion of kazuki's technique on harmed and tells kazuki he is absolutely correct. Kazuki get shocked by seeing diablo casually walking after that attack he threw. Diablo tells kazuki he wants to make a deal, diablo tells kazuki that if he manages to land a blow on him with his eyes closed he would classify him as an A ranked assassin. Kazuki gets frustrated and then charges at diablo, he starts to throw daggers at diablo L. Diablo casually dodges them with his eyes closed and asks him if that's all he can do, kazuki then uses close combat to fight with him.
Kazuki keeps throwing kicks and punches at him but diablo just weaves them as they keep coming. Serena while seeing kazuki fight hopes that kazuki doesn't get hurt and then kazuki uses his spiritual explosion technique to attack diablo. Diablo smiles and tells him if he wants to get stronger then he should push past his current self and then he slaps kazuki's spiritual explosion technique back at him. This blasts kazuki away to some tree's and diablo sighs and says to himself that he shouldn't have gone that far, he calls out kazuki's name and asks him if he's ok but then out of nowhere kazuki just appears behind diablo ready to stab him with a dagger and then diablo just slap kazuki away making him crash into dozens of tree's. Diablo says that he hates surprise attacks and he should do better than that.
While alex was drowning in a river, he tells himself that he cant give up no matter the cause ,he says that if he needs to win a fight like this he has to try harder and then alex jumps out of the water into mid air and says he's not going to lose. Diablo looks at serena's direction and asks her if there is anything interesting she wants to show him, he tells her to hurry up and show what she's capable of. Serena takes a deep breath and tells herself to calm down and then her legs begin to spark out an enormous amount of electricity. Diablo is a little surprised and tells her she is impressed and then she starts to move with the speed of lightning charging towards diablo. She starts to release powerful kicks and punches at him but instead of dodging them he blocks her attack, she is tells herself that with her speed amplification she should be able to do some damage, diablo tells her she has an interesting technique and then reminds her he said non of them could beat him and then flicks her away with his finger. She flies a couple of metres away but she maintains her balance and lands on her feet. She then charges towards him again ready to punch him again but then she sees alex in air ready to land diablo with a punch and kazuki from a far distance ready to punch him. Diablo smiles and says to himself that these kid are something else. Two minutes later alex kazuki and serena were just lying on the floor looking beat up, diablo then say he has something important to tell them, he tells in excitement that they are weak making them look so confused. Alex then asks in frustration who he's calling weak, diablo then tells them that they aren't to but need more training and then he tells them that they all pass. Out of curiosity they all ask him to repeat his sentence again and diablo tells them that their training in order to become very strong and surpass every assassin that has ever lived starts tommorow and then he walks away and tells them to take it serious.
Kazuki says that diablo is more of a good than a sensei. Alex stands up in excitement and says he cant wait to begin training so he can become powerful and become a lord, kazuki lookscat him and asks how a numb skull like him can become a lord. He tells kazuki to shut it, serena sighs and asks herself what she's going to do with these two. Diablo goes to king's offer (The lord of the city who is under his 50's) he asks diablo for the report of the students and diablo tells him that they are a pain but at the same time they look like they all have potentials especially that alex and kazuki. Kojin sighs and asks him to read the report. Diablo says that the students have good fighting techniques and really amazing abilities, he says alex uses a technique called energy fist in which increases his strength and can also increase the technique to a higher level due to his immense energy, he says that alex is also able to flash step not to a long distance but he uses it to confuse his opponent and then attacks from different angles. Diablo giggles abit says that Alex fighting technique is almost as if he is making clones. Kojin asks him about serena, diablo says that serena's ability is electric amplification. He explains that she has the ability to amplify her body parts with electrical energy making her physical attacks faster and stronger. Kojin then tells him to talk about kazuki, diablo starts to scratch his head with a funny expression on his face. He asks diablo what the problem is and then diablo says that kazuki is very skilled but aims to kill when fighting, he explains to kojin that he has a very good iq and is really skilled with close combat but he could use some work.
Kojin sighs and tells diablo that it was a very good report, he then tells him that he is dismissed,diablo leaves kojim's office. As he was walking outside, diablo looks up in the sky and say to himself that he is going to make those kids even stronger so they all wont suffer. Meanwhile Alex is at home playing some video games when he hears the door bell ring, he pauses the game and asks himself who it could be. He walks up to the door and asks who is it and when he opens he sees Baraka and kinto behind the door with lots of food which leaves alex in excitement. As alex was eating the bowls of rice kinto bought for him, baraka asks him how his fight with diablo was, alex pauses with his spoon in his mouth and asks him how he knows him diablo. Kinto tells him that diablo is part of the top ranked assassins in the city and he is really famous among other countries and cities too. Baraka says that it must have been a really hard time fighting with him and alex smiles and says that he was actually very strong and Hope's to surpass him some day so he can be a lord one day. Kinto then smiles and says that alex still has that flare to become the strongest, baraka in amazement see's alex that alex has beaten the boss of the final level in his video. Alex smiles and says that ths level wasn't close to hard at all, kinto picks up the controller of the video game and says he can play it better and alex with a smile on his face tells him to bring it on and they both begin to play the game together
