Rajdhani(राजधानी)(রাজধানী in Bangla) is one of the thirty-six highschool students sent adrift. He is unusually smart for his age, trying to discover the rules governing the new worlds, and a way to get back. Judging from his skin tone and name, he is likely at least part Indian.

His power, called "Pocket Computer", allows him to project a computer program onto the real world.
