Tenya Ida is a straight-laced Class Representative of Class 1-A, whose Quirk is Engine, which gives him super-speed via jet engines in his calves, which also increases his kick strength vastly. Tenya may look severe, unfriendly, and even intimidating at first glance, but he's actually a very straightforward, earnest, intelligent, sophisticated, disciplined, and noble person, although a bit clueless about personal interactions due to his elite upbringing. A testament to his generally hyperactive and intense behavior, Tenya often exhibits plenty of peculiar tics, such as moving his arms around in strange chopping patterns or sometimes twitching his own body uncontrollably, yet he rarely sheds his usual strict expression. Tenya tends to take everything very seriously and is known for his habit of jumping to conclusions, then enthusiastically speaking or acting based on said conclusions. Furthermore, Tenya always attempts to immerse himself heavily into practical exercises, playing his part as a hero or villain in an overly theatrical manner, as an attempt to appear more authentic. Tenya is extremely dedicated to his studies and is always eager to learn new things, regardless of whether they have anything to do with Heroics. As Class 1-A's representative, Tenya is obsessed with organization and discipline, expecting his classmates to follow suit, which more often than not annoys them due to his usually loud and overbearing nature. Tenya is very humble, willing to admit to his mistakes, apologize for rude behavior, and improve himself in areas he is lacking.
