the battle was extremely dangerous and there was no turning back, even though Shion had come along, it was still difficult, until in a moment of defense, Senta protected you from one of the attacks leaving you very badly wounded, you became extremely angry and fought Mu Dan with the others, until they managed to defeat him thanks to some information from Senta

After defeating him, Shion and Senta were extremely serious and close to dying, and Yuzuhira had something that could help, but only one of the two, and choosing Shion, because he was much stronger, even though Sagiri didn't want that, but luckily, you had agreed, because you were a healer, even if Senta was going to die thirty minutes, it was more than enough for you to save him, with that, you separated from the others in a tent with him and stayed taking care of him and doing everything while he blacked out, after two hours, being at night, the impossible happened, he started to wake up and still alive
