Hiroshi Shitsuno's supporters rushed to the headquarters, but part of Muranaka and Kameyo's supporters were blocked from the inside as well. Once the Hiroshi Shitsuno supporters rushed in, these people would block them from going inside.
They knew that as long as Hiroshi Shitsuno died, this group of supporters would be without a leader, and they certainly wouldn't want to die. So, with a little suppression and a little advantage, it wouldn't be hard to find someone to take lead. However, if Hiroshi Shitsuno does not die, then it means that they're supporting the future successor, and they knew that their blood and sweat shed today would be their rewards in the near future if they won. So, compared to Muranaka and Kameyo's supporters, Hiroshi Shitsuno's side was way more high-spirited.
