Heartwarming / Sure as the Setting Sun

• Mob and Izuku's friendship. Just seeing these two awkward protagonists supporting each other and caring for the other when things get tough throughout the story is very delightful to read.
• Just like in canon, Reigen being a supportive father figure to Mob is pure bliss.
  • Reigen escorting Mob to U.A. on his first day of school followed by him taking pictures of his son/pupil to capture the moment.
  • After Mob calls Reigen telling him about his fight with Hitoshi, Reigen immediately takes responsibility for pushing Mob into a situation that approves of excessive violence and assures him that he can quit if he doesn't like it anymore.
  • In the beginning, Reigen intended to use Mob's enrollment at UA to stir up publicity for the Heroics Consultation Office. But once Mob wins the Sports Festival and has to deal with the stressful presence of overbearing fans and the paparazzi, Reigen steps up and forces them all to leave him alone.
• One piece of fanart has Tsuyu helping Mob relax and reduce his explosion meter.
