#2 The day all the dots connected into a line. The reason I was destined to meet MaMo.

Last updated: April 5, 2026

Hello, I'm Etchan.

I am one of those whose life changed dramatically thanks to "Personality Statistics," a method specialized in human relationships.

In this note, I share "what exactly Personality Statistics is" based on my own real-life experiences.

I would be happy if I could deliver a word that reaches those who are feeling uneasy about their human relationships.

In the previous article, I told the story of how, after the despair of taking two leaves of absence, I encountered the light of "Personality Statistics" and regained my true self.
To those who read it, thank you very much.

This time, I will talk about how that small light eventually connected to a future far greater than I could have ever imagined.

It is a story about that fateful "encounter."

The fateful phone call came suddenly.

As I mentioned in the prologue, Personality Statistics was truly the "hope" that saved me when I was in the darkness.

I wanted to get closer to that light of hope, so I became completely absorbed in it.

It happened when I passed the Intermediate Level Communication Certification and applied to upgrade to the Advanced Course to deepen my learning further.

I called the office with a few questions regarding the procedure.
I was just talking to the office staff normally when it happened.

"...Please wait a moment."

The hold music played, and a few seconds later...

What I heard from the other end of the receiver was a voice completely different from the office staff's—a voice I had heard somewhere before, calm yet firm.

"Hello, this is Mayumi Inaba. Thank you very much for your application to upgrade."

For a moment, I could not
understand what had happened.

It was the owner of that very 'voice'
I had been listening to day after day
in e-learning video materials.

It was Mr. Inaba himself, the developer of personality statistics
and someone who was, to me,
a figure far above my reach.

Why was the person himself
answering my inquiry call?

With surprise and nervousness,
my mind went blank.

This was my incredibly shocking and
fateful 'encounter' with my mentor,
Ms. Mayumi Inaba,
who would change my life.

Discovered by my mentor, moving to a new stage

One or two months after
that shocking first phone call.

I was blessed with the opportunity to speak
with Ms. Inaba on the phone
several more times after that.

For some reason, she took an interest in me,
even though I was just an ordinary student.

With a single-minded desire to live up to her expectations,
my passion for learning
burned even brighter.

And then, the fateful day arrived.

That day, just like always,
I received a call from Ms. Inaba.

And from the other side of the receiver,
a single phrase that would greatly change my future
was spoken.

'Ecchan-san, if you would like, why don't you advance to the higher-level "Master Course"?'

Until that moment, I didn't even know
that there was a top-level course called the "Master Course."

With surprise, and even more so,
with the confusion of thinking,
"Is it really okay for someone like me?"
my mind went blank.

However, at the words of my mentor who believed
in my potential,
the best I could do was answer "Yes."

"Won't you build an AI with me?" The shocking offer that changed my destiny

It happened during a phone call one day, while I was deepening my studies in the Master Course.

While I was having a conversation with Mr. Inaba as usual,
words that made me doubt my own ears
were spoken so naturally.

“Actually, I am currently trying to build an AI monitoring conversation system based on personality statistics.”

The moment I heard those words,
a lightning bolt struck my mind.

“Wow! That sounds incredibly interesting!”

I shouted that out,
almost cutting him off.

My own struggles.
My experiences with subordinates.
And the power that personality statistics have
to save people's hearts.

Everything,
I intuitively felt,
connects to this one concept of an “AI monitoring system”!

Perhaps my excitement was contagious.
Mr. Inaba continued with even more
unbelievable words.

“Really! If you'd like, why don't we do it together?”

“!? I would love to!”

Without a second thought,
I answered him.

This single phone call was the moment I will never forget,
transforming me from someone who was merely a “learner” of personality statistics
into a participant in a grand project to

“create a new form of filial piety”

using cutting-edge AI technology.

First mission: Persuade my digital-hating mother

Thus, I became involved as one of the
“core members”of the AI development
from the early days of MaMo.

And as the first user,
I decided to have
none other thanmy own mothertry using this system.

As I touched upon briefly in the prologue,
introducing it to my digital-hating mother
was by no means
an easy path.

As expected, the first words out of my mother's mouth were

“I don't want anything to do with that.”

That was the clear, rejecting response.

It was understandable.

It is only natural to be confused when a machine you have had no connection with until now suddenly arrives at your home and you are told to talk to it.

I explained it slowly to my mother.

This isn't a surveillance camera. All I want to know is whether you are doing well today. So,
could you please talk to it every day, even if it's just one word like 'Good morning'? That alone will let me check on your safety and give me peace of mind.

I said.

Perhaps because my desperate feelings got through to her, my mother reluctantly nodded.

And, from that day on.

As promised, my mother began to speak to the AI every day, even if it was just to say hello.

Two values that turned into conviction

It happened one day after those days had continued for a while.

The quiet emotion I felt when I discovered the fact that, even if she was blunt in her words, my mother was actually interacting with the AI more than just saying hello.

For me, that was the moment I felt firsthand the

two certain values that this project holds.

1. The 'daily peace of mind' I gained myself

The conversation between my mother and MaMo. arrives on my smartphone as a log every day.

That alone allows me to confirm, 'Ah, my mother is safe again today.'

I was completely freed from that blood-curdling fear I felt when the phone wouldn't connect.

2. My mother's 'small but certain hope' for the future

Having a conversation with someone every day
is the best brain training.

This interaction with AI
could lead to maintaining my mother's cognitive function
and might extend her healthy life expectancy
by even just one more day.

'Daily peace of mind' and 'hope for the future'

This system is
not just a convenient tool.
It is the best partner
that fulfills the earnest wish
of a child thinking of their parent.

Convinced of this,
I decided to start
sharing this wonderful value in earnest
to reach as many people as possible
who are struggling just as I once was.

The modest activities I began in this way
eventually led to
an appearance on NHKandthe World Expo,connecting me tounexpectedly
large stages.

I will share that story
in the next article.

Thank you for reading
until the end.
