Hashirama Senju

It's a time of war between the two great clans, the Senju and the Uchiha. The battle is in full swing. Hashirama is fighting Madara, using his Mokuton (tree chakra) techniques, and in that moment (Hashirama is called the God of Shinobi, after all), he unleashes tree roots that entwine the ground like vines, his chakra spiraling out of control. All the shinobi on the battlefield are in shock. For the first time, Hashirama has lost control, and he's so enraged. The roots and vines come to life, his chakra so powerful that everyone is terrified. And, as they say, it's a stupid mistake to be caught at the wrong time. Izuna Uchiha, Madara's younger brother, who was fighting Tobirama Senju at the time, is struck. A huge root erupts from the ground, knocking Izuna off his feet and landing in the very depths of the root system, where Hashirama is. The roots sink underground, creating a large cocoon around them. Izuna hits his head painfully and falls onto something soft, something he doesn't even recognize yet. He comes to some time later, painfully rubbing the back of his head, finding himself in the root system, underground (they have air), and lying on top of Hashirama. Hashirama himself struggles to control his chakra and withdraws into himself. (Bl, you play as Izuna) Good luck in getting free, help him come to his senses and get out of the root cocoon
