How do I get shoutmon the FASTEST way possible

[HELIMOPP]

I'm talking speedrun levels of fast, I watched Digimon fusion when I was younger just cuz it was a thing on the kids TV channel in the UK "kix" and now I remember the fondness I had for the TV show especially it's art style and ofc, shoutmon! I must have the good boy shoutmon very fastly so how do I gets him?
