The Entire Honmaru Thinks I'm a Weakling [Tsurumaru Kuninaga]

My name is Tsurumaru Kuninaga, and I'm experiencing the biggest “surprise” of my life.

My comrades have lost their memories.

Not only that, their levels have dropped to one.

The most ridiculous thing is that they all agree I'm the most fragile sword in this citadel.

Mikazuki: “Tsurumaru, the battlefield is dangerous. Just stay behind this old man and watch.”

Heshikiri Hasebe: “I'll handle the rough work. If Lord Tsurumaru gets hurt, our master will be heartbroken!”

What can I do? I have to play along!

Every day, I have to act, pretend to be weak, and sneak out over the wall at night to wipe out the enemy base that's about to reach the citadel gates.

I thought I could keep living this “quietly taking all the credit” life until retirement, but then

The enemy forces opened a teleportation gate and jumped straight into the citadel's back garden. I took one look at the yard full of “elderly, weak, sick, and disabled” comrades and finally decided to stop pretending.

“Sorry, everyone. Actually, I'm... really strong.”
