Gu

Before he left, he took a few things with him. 

A nutrient potion.

A stamina potion.

And more importantly…

He pulled a fruit out of his backpack.

It was white.

Transparent.

Ethereal in its physicality.

A fruit from the Tree of Healings of the Sekigahara Confederate.

He had carried one for good measure on his entire journey, having reserved it for the one and only one moment he would truly and absolutely need it.

He had abstained from using it in even the most dire situations. 

Not when he fought the Terrampager.

Not even when he fought against Sage Sekiei despite having plenty of opportunity to consume it before the fight began. And yet, this time, in the face of a battle to the death with some of the most fierce warriors in the Gu, he didn't hold back.

He immediately consumed it.
