My Period Started!!!

That hit the spot~

Two hours later.

Tsunade finished her bath, changed into fresh clothes, and came out of the bathroom thoroughly satisfied.

Her damp blonde hair hung over her shoulders, still giving off steam.

She stretched, feeling comfortable all over.

"Nothing beats a little fun in the bath~"

She walked toward the bed, drying her hair as she went.

She had trained, fought, and saved someone today.

Now all she wanted was to collapse onto the bed and sleep like the dead.

Tsunade reached the bed and had barely sat down.

A familiar yet strangely foreign ache suddenly gripped her lower abdomen.

"What's going on?"

Tsunade frowned and instinctively looked down.

Then she saw it on the fresh pants she had just put on.

A small, dark red stain was slowly spreading.

"What the hell?!"

Tsunade froze.

"Did I rub myself bloody?!"

Her first thought was that she had gone too hard in the bath.

Maybe she had hurt something.

After all, she still wasn't fully used to this body.

It was possible she hadn't known her own strength.

Panic surged through her.

Without another word, Tsunade raised her hand, and green Chakra light poured from her palm.

Mystical Palm Technique!

She pressed her hand to her lower abdomen. Chakra seeped gently into her body and began repairing the wound.

But the bleeding didn't stop. It got worse.

The dark red stain on her pants spread before her eyes.

Tsunade felt awful.

"The Mystical Palm Technique isn't working?!"

"Am I going to die?!"

"I've only been in this world for half a month, and this is how it ends?!"

Her head buzzed. She was about to shout, "Grandma, help!" when she stopped.

Wait.

This feeling...

This spot...

I'm not hurt!

This is...

That thing women get once a month.

My period!

"Damn it! How did I forget about that?"

Tsunade's face twitched, her expression complicated beyond words.

For a woman, this was perfectly normal.

But for a "boy" who had spent more than twenty years as a man in her previous life and arrived in this world only half a month ago?

Everything about it felt wrong!

Physically, she was a girl now.

But deep down, she still thought of herself as a man.

"How long does this last?"

Tsunade took a deep breath, closed her eyes, and quickly searched through fragments of the original Tsunade's memories.

A moment later, she opened her eyes. Her expression grew even more complicated.

"Usually around five days. Irritability for no obvious reason, and strenuous exercise is best avoided."

"So that's how it is..."

Tsunade rubbed her chin as realization struck.

"No wonder I hit Jiraiya so hard earlier!"

"One punch broke six of his ribs and made his internal organs bleed."

"So I was already irritable because my period was coming?"

She scratched her head, feeling a little guilty.

But that guilt was soon replaced by a more pressing concern.

"This is a problem!"

Tsunade frowned.

This was one of the frustrations of being a female ninja.

Depending on their constitution, women had a few days every month when their fighting ability dropped sharply.

Five days wasn't too bad.

For some, it lasted seven or eight.

"This won't do!"

"Five days without intense exercise."

"How am I supposed to train?"

Tsunade shot upright. Another cramp seized her stomach, and she grimaced, clutching her lower abdomen.

She was determined to become a master of Taijutsu.

To unite the Shinobi World.

To bring every beautiful woman in the world to Konoha!

If she couldn't train for five days each month, and even other kinds of practice took twice the effort in that state...

That was sixty days a year. Half a year over three years!

Was she supposed to let all that time go to waste?

"No! Absolutely not!"

"This is going to hold me back!"

"Could I... stop this thing?"

Tsunade muttered to herself as her mind raced.

There might be a way.

She remembered reading about methods for stopping menstruation in her previous life.

The first was the simplest and most direct.

Pregnancy.

That could stop it for roughly a year.

But Tsunade wouldn't choose that if her life depended on it.

"Then... the second option?"

Tsunade rubbed her chin and kept thinking.

"Surgery?"

She wasn't ignorant of the Shinobi World. She had come from another world.

Surgeries to stop menstruation had existed in her previous life.

There was an endometrial ablation procedure developed specifically for women with extremely heavy periods and persistent anemia.

It was minimally invasive.

It could greatly reduce the bleeding.

But it caused irreversible damage to the uterine lining.

And most importantly...

"I don't know how to do it!"

Tsunade slapped her forehead.

It wasn't just her. There probably wasn't anyone in the entire Shinobi World who could perform that surgery!

However advanced Medical Ninjutsu was, it treated external wounds, internal injuries, poisoning, and broken bones.

Who would spend their time researching how to stop women from having periods?

Tsunade's eyes suddenly lit up.

"If Medical Ninjutsu won't work, what about Sealing Jutsu?"

Sealing Jutsu in the Shinobi World was incredibly powerful.

It could seal water, fire, tools, Tailed Beasts...

It could even seal a monster on the Nine-Tails' level.

Sealing one little period should be easy enough, right?

"That's it!"

Tsunade slapped her thigh, excitement rising.

"I'll develop a 'Period Sealing Technique' and seal my period away!"

The more she thought about it, the more feasible it seemed.

"It's decided! I'll start by developing a Period Sealing Technique!"

Tsunade nodded firmly and stood to look through the Sealing Jutsu scrolls Mito had given her.

But—

The moment she stood, dizziness washed over her.

Her vision darkened, her legs went weak, and she nearly fell flat on her face.

"Stood... stood up too fast?"

Tsunade gripped the edge of the bed and shook her head.

"No. That's not it."

She lowered her head and looked at the floor.

Then she froze.

In the few short minutes she had spent thinking...

She had bled all over a large patch of floor.

Dark red liquid spread across the boards. There was an alarming amount of it.

Gulp!

Tsunade swallowed hard.

"This... this much blood..."

She quickly searched the original Tsunade's memories.

"This has never happened before!"

The original Tsunade had suffered cramps, but her bleeding had always been normal.

Nothing like this.

"Looks like I really overdid it these past few days."

Tsunade immediately felt guilty.

Thinking back, how had she spent the last half month?

She got up at four in the morning to run, covering a hundred kilometers at a time.

In the morning came strength training: lifting rocks and striking wooden posts.

At noon, more conditioning: frog jumps, push-ups, and sit-ups.

In the afternoon, she practiced Chakra control by climbing trees, walking on water, and working on fine control.

At night, she studied Sealing Jutsu with Mito.

Twenty-four hours a day, she barely stopped.

Her Senju and Uzumaki heritage gave her a powerful body and astonishing recovery.

But even that body couldn't take this kind of punishment!

And then there was what she'd done in the bath...

"Ahem!"

"Looks like I pushed my body too far. That threw my period off and made the bleeding much heavier."

Tsunade held her aching lower abdomen and sighed.

"Even the toughest body can't take being trained into the ground."

She looked around the room and began searching in earnest.

First, she needed to find something to stop the bleeding.
