Yes! YES! First Prince Hata and now Hedoro. I was right thinking even Hata and Hedoro had backstories. Now I wonder if there would be another plot twist or two by Sorachi. Maybe like featuring the Ketsuno clans and their rival joining the battlefield in protecting the Earth? Or Hoichi with his cat armies? Or Ikeda Yaemon? Or revealing who Hatsu Hasegawa really is and she brought a massive army of Madao?
Hell, at some points, I even have a thought that Shigeshige was never truly dead, but it was all a plan by Matsudaira to trick Nobunobu to make it even easier for them to have allies and rally more troops, but they marched with these new allies and troops not against Nobunobu, but the Liberation army. And then everyone would go 'SHO- SHO- SHOOOOGUN KAAYOOOOOOOOOOO!!!' *plays Shogun Assassination main theme*
Another thought is Isaburo was never actually dead either. When he fell from the plane, he fell to the sea, to his surprise, he was still alive. Then he healed himself, and stayed to wait for his wound to fully recover. When he finally set sail, he arrived at Edo only to find Edo was obeliterated. He fought the Liberation army, and he found a handphone. He texted Nobume and replied her message with the phone, surprising her to her very bone. Nobume tried to find Isaburo, and she succeeded and found Isaburo sitting on a knocked out Amanto while texting with dead-fish eyes on his face. They finally reunited, and Nobume hugged Isaburo like a daughter hugging her father. *tearjerking intensifies* Then they returned to the battlefield, and kicking Liberation army's asses side by side with Jirocho and Pirako.
I perhaps could only hope. But let me ask you all, could all these really happen?
