Here is an explanation of the characters featured in S.KT. content (such as S.KT. Music and S/KT.).I believe this is the kind of thing you should tackle with momentum and confidence.
S.KT. Music
Concept Character
S.KT.

<A creator who continues to make music as an extension of their hobby>

Japanese First Person Pronouns: jibun (“自分”)
The entity closest to the person behind the scenes.
Please refer here for information regarding the person behind the scenes.
Please refer here for information regarding the person behind the scenes.
The premise is that this character oversees the direction of all characters—starting with TTKT—and coordinates their activities.
Origin of the name: Derived from the person themselves. “S” and “KT” (from TTKT).
TTKT

<A creator who continues to take on musical challenges as an eternal beginner>

TTKT is the alias S.KT. uses when taking on new challenges. It is primarily used for the irregular “10-minute composition” series, where the persona adopts the stance of a “beginner.”
It also serves as an alias for activities not officially classified as music. For some reason, it is also used for illustration work—an area where the creator is likewise a beginner.
Origin of the name: A play on the spelling of “PPAP (Pen-Pineapple-Apple-Pen),” a song by Pikotaro that was popular at the time. The letters T and K were chosen based on the creator’s own name.
DonKei

<A singer who crafts enigmatic lyrics>

“DonKei” is the alias primarily used for vocal tracks (produced by the artist themselves).
In recent years, there has been an increase in appearances solely as a vocalist or as a lyricist.
…At least, that is the official persona—even though, within S/KT., the artist performs under the name “S.KT.”
Origin of the name: A combination of “Don” (from the game Taiko no Tatsujin, which the artist used to play) and “Kei” (K).
Sekkita

<I'm dying to sing!>

An UTAU voicebank created from the voice provider (S.KT.) out of a sheer desire to make the voice heard.
TTKT handled the direction (or so the backstory goes).
He made his debut in “Insiemusica” and later took on lead vocals for “Theme of Sekkita.”
Having seemingly wrapped up its initial mission, his future appearances are expected to be sporadic.
He is available for download, so please check it out if you are interested.
Origin of the name: Derived by assigning vowels to “S.KT.”
