After clearly losing my sanity a year prior, I began researching on ways
to conceal myself on the Internet, because having my legal name exposed
was nowhere near an option anymore.
Given my own subtle interest in astronomy, I have had settled on the nickname 'Nova'. 
Months later, I had gotten closer to a person from a Telegram chat, and earned
the nickname 'Champagne Supernova'. 
I've been like that for about two years.

(Year: 2022)
For some rather odd reason, I felt that I did not want to be called
'Nova' anymore, and made up another name, that being 'Aoi Koizumi',
It was based off one of my avatars I had made and published on
Pixelfed and the last name of a character from Haruhi Suzumiya
(the franchise). 
That happened around my early 21s. 
When I was in charge of KyokoNet and ShellTalk (IRCNow), I used that
name. 
By then I was already retired from ActivityPub. 
It eventually turned out to be a mistake as I realized that 'Aoi'
is typically used as a name for girls, and I was not going to
pretend to be otherwise....

Around the end of the month of April, while I was gate keeping
an abandoned house by then, I had an odd dream, Yukari Yakumo
appeared on it, and proposed me to be her servant, just like Ran and
Chen.
When I woke up the next day, I've had renamed myself as
'Izuru Yakumo', and proceeded to erase any trace of
'Aoi Koizumi' online and replaced with my new identity.
When I turned 22, I also had realized that I wanted to
be a hermit and live in seclusion from society, and
this name, once I found out what meaning it had, it
kind of fit me like a ring in a finger. 

If I eventually succeed in my life goals, I may
eventually adopt it as my real name, because I'd
like to be forgotten, in order to live a quiet
and peaceful life.

To this day, while I still have the username
'novaburst' and the 'Champagne Supernova' nickname,
I only keep them because I kind of like them.

That's all.
