Me and Mr. Noir were walking in the woods, guided by Mr. Tico.

"What exactly do you do with training?

I found out that the training ground was the stronghold of the Dark Emperor, but I don't know what to do there.

"Aren't we going to fight the Dark Emperor?

"Exactly. I guess we won't be resurrected again."

The body was shattered in the Devil's Forest, and the soul was shattered during the trial. I've seen it become a Buddha, and I'm pretty sure it's not a training called "Fight the Dark Emperor".

You have to walk the Demon King's stronghold.

"Dark Emperor" The Demon King's stronghold is all over the world. One of them is this forest cave.

Apparently, the Demon King was manipulating many demons with brainwashing magic, and it's not strange to lurk in a cave in case that remnant should come.

"So you're walking while defeating the remnants of the Demon King's Army in the cave, right?

It's just too easy to walk.

Tiko's training is the goal of defeating the demon king's men who push him.

"There are many demons in the cave, so there will be battles. But the important thing is to walk."

Are you saying that fighting demons is only a matter of time?

"But are you going to train just by walking?

You might get about your strength, but what I want is magic.

"It's not just a cave you walk in. It's the longest cave in the world. Besides, it's a dark, very scary place."

Mr. Tico highlights' World's Longest 'and' Dark '.

"Humans are creatures that grow by beating negative emotions like anxiety and fear. Not physically, but mentally."

That much was explained, and I finally understood.

Build your spiritual strength to increase your magic.

I mean, Mr. Tico's training is called "Building Mental Strength by Beating Fear"!

The base of the Demon King is a good place to have negative feelings!

"Mr. Tico got stronger with that training, didn't he?!

"It doesn't mean the exact same training. I'm a light magic user, so I brightened it up like daylight instead of dark."

"So you're going to be training?

"Even if it's bright, walking in a cave that you don't know when you're going to get a goal is all that scares you."

I see. Did Tico get stronger by confronting the fear that he might do all he can before he scores a goal?

"But you're not going to feel a little scared."

Surely 'the longest in the world' is not enough.

"That's why you added a condition called 'dark'?

"Yeah. Plus I forbid you to bring food. No matter how strong you are, if you keep walking without drinking and eating, I'll do my best one day. Or are you not going to die doing anything?

Do they think I'm a monster or something?

"I'll do my best."

I guess that was when I was ten. When Grandpa Maurice wanted a magic wand (Wizards Rod), he had been returned saying, 'Now I'm going to work out my body anyway'.

I wanted to get my magic wand quick, and instead of sleeping, I decided to spare myself a meal to train.

I just trained without drinking or eating for three weeks, and Grandpa Maurice stopped me worrying... if I had trained without meals like that, I would have died one of these days.

So I can live without drinking or eating for at least three weeks, but I don't know how many days it will take to get to the goal.

Maybe I'll do my best along the way.

Beating that fear will make me stronger!

Mr. Tico suddenly stopped as he walked as he burned a flame of motivation.

"Come on, we're here. This is the base of the Demon King - the longest cave in the world."

There was a staircase leading to the basement in the gap between the trees.

I imagined a normal cave, but was it an underground cave? I can't imagine how long this is going to take.

Even so, my resolve remains the same.

No matter how long the cave is, one day we'll reach the exit.

And when I score goals, my magic is growing exponentially!

"When will I see you next?

I was just about to step into a cave, and Mr. Noir grabbed the sleeve of his clothes and looked anxious.

It's the same situation, and maybe you remember something between trials. It took me ten months to return then.

"I don't know when, but I'll definitely be back!

"... really?

"Really! I will definitely come back alive. I'll make you look good. So, Mr. Noir, show me how you're doing. Eat a good meal every day and live a regular life."

I was on an insomnia break without drinking or eating. What am I supposed to say?

"I'll have dinner till your minute. The next time I see you, I might be older than you."

You're trying to soothe me, Mr. Noir said in a joke.

Though, you can't say it's a joke, can you?

Mr. Noir is growing up - when he eats, he only grows what he eats. In fact, I grew more than 10 centimeters in ten months without me.

"I'll have to buy some new clothes then."

"I look forward to shopping with you."

Mr. Noir releases his hand from the sleeve of his clothes to see if his anxiety has subsided while he is in conversation.

"Okay, I'm coming."

That's how I smiled and said goodbye, and I stepped into a dark underground cave.
