surprises people with his magic/genius. He makes a groundbreaking rice cooker. His duty is to eliminate a reincarnated hero who has many more cheats than he does but he is an assassin so ez pz. Unfortunately nothing about MC personality wise stands out and everyone else is one note. The overindulging parents, the Loli teacher, nothing new. For that I give it 3 stars as it doesn't do anything bad but it doesn't do anything great either.
For example in a relay race he uses a Thailand technique (i think) and many including himself recognize he used it for his own to win. He even acknowledges them as pioneers in the relay race.
