This is good. I have read the first 3 chapters.
Fast-paced at first, but ok. The base is simply presented. Someone from the future breaks into one's past life.
The main protagonist doesn't fill out aspirational career forms, spends time having fun and feels left behind when the people around him mean it (play ball for the pros, and his friends are busy taking cram school).
I'll just outline it. He will be targeted by Vortex who intends to kill and claim his technology. The Manager goes back to the past to help his president, the circumstances in the future are on the verge of bankruptcy. And the goal with the Manager is to look and recruit for 3 legendary individuals who are 20 years old from now will have a big influence. Even to mention the value is more than any living national treasure.
After that the execution is executed as predicted, quite balanced, even there is an interesting action. Especially the manager (
Sakamoto, is that you?) is very elite when using his business card as a weapon.
What I like from this manga is
having a clear purpose. At least there is a reference to where the story goes and flourishes.
I like to see his expression in the first chapter :
Lol, the comedy is pretty funny.
*again, I don't want to be hopeful*
