"What?! My brother was possessed?"
The three who had just returned were chatting and laughing, but Tobirama flew into a rage the moment he heard what they said.
"When did this happen?"
"Isshiki possessed him using Kāma?!"
As he listened to Tetsuhiro explain, Tobirama's expression grew increasingly grim.
"Relax. We already banished him."
"Who can be sure about something like this? Just like this guy said, what if?" He pointed at Madara.
Madara immediately snapped back, "Hey, show some respect."
"..." Tobirama silently lowered his hand.
Then Tobirama sealed off the Research Institute and began examining Tetsuhiro right there.
More precisely, he examined the Kāma on Tetsuhiro's left hand, with Kaguya assisting while Madara activated his eyes and observed throughout.
A month passed...
Tetsuhiro lay on the cold Experiment Table, instruments hooked up all over his body.
Outside the Isolation Room's transparent glass, Mito, Shu Mao, Reiko, and Mai Valentine quietly arrived to visit him.
Tobirama stood deep in thought before a monitor, while Kaguya and Madara remained on guard throughout.
Shinnō, Orochimaru, Hiruko, and the others were busy analyzing and recording data.
"Hey, what's with those expressions? I'm fine," Tetsuhiro said with a smile behind his mask.
"Hashirama..."
"We're at a critical stage. No talking," Tobirama interrupted brusquely.
"..." Helpless, Tetsuhiro turned back and lay flat again.
"Hmph!" Kaguya paid no attention to that and asked anxiously, "Tobirama, how is it going?"
"Based on the information you provided and our research over the past few days, I've established several things, but we'll discuss them later," Tobirama said gravely without turning around.
Another hour passed...
The analysis was nearly complete, and they moved on to breaking the seal...
The initial attempt failed...
A second attempt...
The second attempt failed...
They changed procedures, adopting a backup plan: an external assault
