But that didn't mean that Allen wouldn't remove the spy gadgets in his classmates' houses since he wasn't that selfish especially when he had just told his classmates earlier about the existence of the spy gadgets.
Allen's plan in doing that without the Supreme Academy suspecting his classmates of defying them alongside Allen was quite simple.
'Why not remove or destroy all of the spy gadgets on the Supreme Island including the ones at his classmates' houses?'
By doing that, Allen wouldn't have to worry about his classmates being in trouble because of his mistakes.
He could destroy all of the spy cameras and microphones manually without getting caught using the <Supreme > talents within his <Supreme Order> talent such as <Supreme Ninja>, <Supreme Spy>, <Supreme Espionage>, <Supreme Secret Agent>, etc.
