Thanks for the chapter!
Due to a mistake from the MC understudies had to replace the eagle and kid. After all, having a firebird and a young imitation of the Human Torch from Fantastic 4 running around is dangerous. That and they'll need to eat at least 5 portions every meal to replenish all the energy and food they've burned off.
Seriously though, it's good he's able to help both the eagle and kid but should've gotten kid's and grandpa's permission first. That type of thing where even a minor mistake could have serious repercussions. MC's lucky grandpa didn't interrupt or startle him or the kid woke up and started thrashing.
