Everything went as they wanted. They decided to attack when Kirishima's big brother not will be there to help them because they didn't want to go against three of the same class as kirishima is. After that they decided the plan and then again started the training.

Nearly 5-7 people say no to Kirishima's idea because it wasn't as easy as it looks. What if the plan fail?what will If there is another one who is spying us and will report then about us? Kirishima can't force his people to die for him.

Everyone can decide on their own he said and then went to his room. After that Hinata and Yotaro went to Michel place for practice. After the practice is over Yotaro asked him if you(Michel) decided not to come again to the underworld then why did he come back to the place.

He smiled and answer to kill those who killed my family. He added the world is cruel. They (the world)didn't give us a second chance no matter how much you suffer you can't undo your past. Yotaro wasn't able to understand that. After that they decided the time to attack the main castle of green gang. Kirishima's older brother was away to do some work.

So then Yotaro had a question will he be able to kill his own father.? But he can't directly ask him about that. The day finally arrived. Everyone was excited. They call their family and their lover because that might be the last time they can talk to them. The time finally arrived.

Kirishima started to talk Right now is the only time you can back off. If you didn't back off right now then you can't blame me if anything happens to you at the castle. Everyone was excited as well as frightened.

They know what they have to do and If they failed then they can't live because that's how the boss S means Shogo works. After that they went to the main gate of the castle. As they decided they went straight to through the main gate. They didn't give time to them to recover and they start. The leader of that group was Hinata.

After that Yuki, Yuro, Fred, Mitobe, Kirishima, Yotaro and Michel went ahead of them. They know that the remaining can't win against them, but they also know that they were ready to sacrifice. As they went ahead and ahead. They saw an old person. Yup he was the same old person Yotaro talked with when they had an offer. Yotaro thought he was in trouble and try to help him but Kirishima stopped him.

He told him to look on the upper right side of the area. There were wires everywhere. Those were the special wires which will cut through your body. That was the specialty of him means This old man known as Seiji. Mitobe told everyone to go ahead without him. No one questioned him except Yotaro who didn't want to leave him alone. But they grab him and went ahead.

As Kirishima, Michel, Yuro, Yuki, Fred and Yotaro moving forward, Yotaro can't stop arguing of the decision Kirishima made. Everyone was ignoring him and that's why he kept scouting. When he calms down Kirishima said So finally you stop talking eh? This time Yotaro didn't reply. You know how hard he trained during the last few weeks all to defeat that old man. You know that old man was the one who killed Mitobe's parents.

He didn't know who exactly did that, but he was one of them and my grandfather was who was ruling the underworld that time. After that Yotaro finally understand. You haven't forgotten me, have you ask Mitobe. The old man smiled and said I remember you very well. Then were you the one who killed my parents he asked? He added I can't completely deny that, but you can say in an indirect way. After that They started attacking each other.

The traps were laid by the old man through the whole castle up to a point. The only thing Mitobe has more than him is his physical strength. As the fight goes the old man started to feel the pain. Seiji said should we take a break, you wouldn't say no to an old man, would you? After that the old man said Sorry for what we had done on that day, we knew that your parents had nothing to do with that but that were the orders of the boss.

Mitobe asked you told Yotaro that Kirishima's grandfather was the strongest then who was the one who killed him, doesn't that make him stronger than him. The old man smiled and said The stronger one doesn't always win. The great power has his own issues. Your own comrade doesn't trust you because of the power and they are the one who really wants you to disappear.

Now let's end this he added. Come at me like you want to kill me. The talking stop and they both were both looking for an opening. As the old man was more experience he knows what he needs to do. So he doesn't have any other option than to attack him. After that he know if he has any chance to win then that should be in close range.

After that he charges straight forward. He made a fake run to try to lure the old man but the old man didn't fall for that trick. The more time it takes it will help Mitobe, but he wants to end his as early as possible, so he can help the other one. The old man was waiting for a correct opportunity but Mitobe was also experienced and wasn't given him too many chances. After that the final movement arrived. They come to attack each other but due to his physical form he was able to dogged it but not completely. After that he was able to hurt him on his organ. Before his life ended he said something in his ear. And he finally takes his last breath. But he was also able to injure him so bad that he can't go to help his comrade and he sat on the floor.
