Maybe the creatures ARE:

maybe he be raising alot of baby legendary beasts (▰˘◡˘▰) i hope.... he gonna be a father?

im pretty sure the legendary beasts would be the four guardians:
red phoenix/vermilion bird
blue/azure dragon
black turtle/tortoise
white tiger

so is he gonna have them 3?

I think so too maybe going toヾ(☆▽☆) be more?

But hes gotta be single for sure!(๑•ㅂ•)و✧

uhhh idk but it feels like he'll be collecting them all if the legendary beasts have babies and are in a similar situation as the phoenix (ノ≧∇≦)ノ (tho im only guessing the legendary beasts are the four guardians cuz its kinda a classic in asian webtoons/manhua/manhwas)
