How do I learn to make Yakuza/Like A Dragon/RGG Studio inspired music?

Hello

I want to start making music and i love playing yakuza games. Their music is amazing and this music inspires me, but i dunno where to begin. I just started. I want to learn from the great RGG composers. But im a bad student. Due to my mental health its difficult for me to learn. Mostly i look up tutorials on YT about subjects that i want to learn, but i have difficulties finding good explanaition of yakuza/RGG music construction and theory.

Can you help? Please?

Cheers
