Personality

In reality, Isaac has shown to be a very treacherous cold-hearted individual with deceitful nature that he won’t hesitate to manipulating anyone, even his friends if necessary in order to make his task easier.

Despite his perceived intelligence, however, Isaac was shown to be a wary hypocrite as he's being cautious of others when he keeps voicing his suspicion of Suzuki's secretive behaviour and making his team to believe that he's leading the Special Attack Squad into a trap, even though he is the one luring them to their doom since he's actually a mole for the Cult.

Like most people who work for the Cult, Isaac had confident in himself and his own abilities. However, due to his overconfidence, he seriously underestimated "Suzuki" and this eventually led to his death.

Genius Manipulative
Isaac was an extremely intelligent and cunning, as he tends to come up with twisted schemes of ingenious and imaginative plans, such as spreading his deliberate propaganda about Shadow Garden's infamy in order to making every student to believe his statement and he was shown to be a brilliant agent of deception, managing to successfully manipulate his friends from discovering his true affiliation towards the Cult during his time at the academy which he won’t mind for luring his team into a Cult's trap.
