Hiro is busy preparing for the showcase while also helping his aunt in the café, but life changes when he keeps having nightmares about a fire and a voice telling him to keep holding on to his brother and to never let him go because once he does he will never return. Now with Hiro clinging onto his brother for dear life, can he save him from something the nightmares may foretell?

Tadashi died, or so it seems. Hiro is just starting to move on with his life at SFIT when he suddenly receives a call from the police, informing that Callaghan wants to see him. He eventually agrees, expecting nothing but the worst from his former foe. In truth, however, he is unprepared for what truly lies ahead...and behind the entire saga all along.

This is a story that follows the plot of the movie, though it goes a little different. Tadashi survived the fire, but it ends up with Hiro majorly injured. So now, while figuring out who stole Hiro's microbots, Tadashi still needs to look out for Hiro. What if something goes wrong during the chase after Yokai, and ends up with Hiro being permanently injured?

Eight months later, Tadashi is found alive, still buried in the debris. But there is a bitter reunion with Hiro, for Tadashi is not happy that his brother is risking his life to be a superhero. As the tensions rise between the brothers, they still must find out how Tadashi survived all this time and investigate the new villain making it's way around San Fransokyo.

The last time Hiro saw his brother, it had been two years ago when he ran into that burning building and died. So why was he here now, standing in front of him like everything was fine? And, more importantly, where were they? (Set 2 years after the movie.)

Hiro has the house to himself for a few hours, and completely ready to spend the day with gummy bears and his DVRed shows. He's not ready for a panic attack to hit him. He's also not prepared for Tadashi finding him hyperventilating in the living room.
