Fight

 After all, Eric was on an undercover mission being the current model student. If Eric showed his ruthlessness, he would surely be feared by his peers. So, Eric would just fight normally like this, he thought.

 At least, that was the message from Rafael that Eric remembered until now. His brother once said that Eric had to look weak in front of his opponent, so that his opponent would not be too wary of Eric.

 Rafael also said that Eric would grow up to be a good young man as expected by their father. Rafael forbids Eric to misbehave. Only Rafael is naughty. Rafael wants to see his younger brother become the proud son of their father.

 Rafael promised to turn into a good and obedient child too. But, before the promise was realized, Rafael had already left this world.

 Remembering that, Eric became sad again. For that reason, Eric made Rafael his teacher in the field of fighting.
