Pokemon: Recruit Ash as My Sidekick?

A bird with dazzling feathers swept across the sky. Was that a Pidgeot? An elegant Goldeen lazily swished its tail fin. Wow, I really want one. An Emolga with bulging cheeks hugged a Berry and munched happily, eyes narrowed in bliss. So cute! “Ding! Congratulations, Host! You've activated the Pokemon Trainer Master System! This System will help you catch the strongest Pokemon in the Pokemon world, complete the toughest achievements, and cling to the biggest powerhouses!” Su Mu woke from his coma and gazed at the wondrous world around him in disbelief. The voice ringing in his mind was an even bigger shock. Had he transmigrated, and did he have a golden finger too ◝₍ᴑ̑ДO͝₎◞? It even looked like the Pokemon world he'd loved most as a child! Huh? But why was there a silly-looking little kid beside him!? This is the author's first work, so please give it plenty of support (⌯︎¤̴̶̷̀ω¤̴̶̷́)✧︎
