Chapter 336.1. Taira Masakado

Taira Masakado’s dungeon exists as a hidden dungeon, with a level far surpassing that of the final boss, Ashtaroth. 
Of course, this is not a setting from the original work; it’s what you’d call a hidden boss in a game. After you clear it, it’s a gift from the developers, encouraging you to explore the hidden dungeon. 
It’s an ordinary pattern in games. The hidden dungeon is so challenging that it treats previous bosses as mere fodder, and the drop items are incredibly good. 
It’s a place for grinding, an existence solely within the game.
It should be that way, but it existed in reality as well. 
Sensing the meaning behind it to some extent, Mii-chan and the others had reached the deepest part.
The inner chambers, where various bosses awaited on the way, had all been defeated through the cooperation of Yamiyo and the others. The intense battles had raised everyone’s levels considerably.
-Teijou Yamiyo: Level 81-
-Aburage Tamamo: Level 83-
-Genshin Sena: Level 90-
-Harukaze Hoku: Level 66-
-Akita Sei: Level 99-
-Natsui Nan: Level 65-
-Nimue: Level 99-
-Moriko Ranko: Level 58-
-Takano Miu: Level 146-
Everyone had become quite strong. Leveling up in the hidden dungeon is indeed efficient. You have to defeat Diamond Poyopoyo; otherwise, this is the best place for leveling up.
Even after defeating monsters throughout , Mii-chan’s level had only increased slightly, and she felt disheartened.
“…Mii-sama, for some reason, it feels like I’m getting stronger the more I fight…”
“Surely, during battles with formidable enemies, Yamiyo-chan and the others have improved their tactics!”
“Hmm, the power of my magic has clearly increased.”
“We’ve become more efficient in using mana!”
Yamiyo and Tamamo had puzzled expressions, but she thinks they’ve definitely powered up through the experience.
It’s not because of Mii-chan’s influence. It’s definitely just a coincidence, a coincidence.
Everyone exchanged looks and smiled wryly as Mii-chan vigorously waved her hands to emphasize her point. They clearly didn’t believe her at all.
Mii-chan’s platinum threads have been infiltrating her friends’ bodies in a significant amount instead of the golden threads each time she uses [God Heal]. 
It’s harmless, so it’s fine. It’s just that their very being in this world has changed a bit. 
Mii-chan won’t use it to brainwash her friends or turn them into servants to change their personalities!
However, Mii-chan’s power may have been poured in as a bonus. 
System-san, System-san, we don’t need a level system for humanity. Can you tone it down a bit?
I prayed to the heavens, feeling a bit of anxiety. It seemed like something might go wrong if things continued as they were.
-Removed the ability to infuse magic power for the new types from Mii-chan’s [God Heal]-
System-san corrected right away. It’s a relief. It’s a nerf, but it’s not a big deal. And maybe, because magic power had been added to their mana, that’s why everyone had powered up.
It’s good that I noticed. Even without that hidden ability, Mana
Awakening is already an incredible ability. It’s a good thing it didn’t activate it.
“Alright, shall we head to the deepest part now?”
“It seems like the Elderwood Dragon from earlier is the last guardian.”
“All the bosses here are made entirely of trees.”
“I have a hard dealing with plants, so this is troublesome.”
Nimue expressed her dissatisfaction with the enemies, grimacing. Ranko-san raised her eyebrows, puzzled.
Nimue, who mainly uses water magic, seemed to have a natural aversion to plant-based monsters here. Well, she got defeated by a user of plant magic before, so she had a complex about it.
“So, Taira Masakado’s curse summons plant monsters, huh…”
Finally, we arrived at a place with numerous splendid sliding doors, and it felt like being inside an animal’s entrails, with vines crawling densely on the sliding doors, handrails, and the ceiling.
Gently placing my hand on it, I opened the sliding doors forcefully with both hands. I had wanted to try opening it like this at least once.
“Hello~. The party of heroes has arrived~.”
Mii-chan greeted in a sweet voice that resembled a bird’s chirping.
“To think that someone would come this far…”
Unnaturally, beyond the sliding doors, there was a vast cave. The floor and ceiling were made of obsidian, sharp enough to cut you if you fell.
Vines were concentrated in the back, forming a mass, and in the center was a thin, emaciated figure with only the upper half of his body protruding.
He was wearing a beautifully crafted war outfit and had a black hat on his head. It was likely enchanted with powerful magic. It was pristine, with no fraying.
But once, he must have been handsome. His face now consisted of just bones and skin, like a skeleton. His eyeballs were the only prominent feature, bulging out, and jagged teeth peeked out from his mouth.
“You must be Taira Masakado! Mii-chan will purify you every day. So be prepared!”
I declared firmly, pointing my index finger at him. He would resurrect after a day. It was a daily task to defeat him in the game. And there were plenty of drop items!
In the game, this is where we would scream, and the Taira Masakado battle would begin.
