Saying This jiro didn't stopped there for a second and leave.
In the way someone asked "brother jiro why did you asked for a death match, we could have just beat him up there". Someone asked in confusion.
Not only this guy most of the people who was with jiro become confused. Why did he have to ask for Death match when so many of us gone!
"I have some old problems with him. I need to resolve that once for all" said jiro and didn't explain further.
He didn't said what the reason he is so desperate he didn't explain why he have to arrange a death match at all.
No one also asked about was the reason anymore. They are indeed interested however they don't dare to ask anymore. And decided just to follow what jiro said.
The reason why jiro asked for Death match is because he. Didn't want's to see Ayan anymore. It's been 2 time he has to face humiliation in the hand of Ayan.
