"Boku No Hero Academia" Chapter 77 is already online courtesy of Manga Fox. The latest chapter continues the story of the students and teachers who are under attack by the Villains Alliance.
Before discussing the spoilers, here's a recap of the latest chapter.
The chapter starts with Tomura thinking about his plans for the Villains Alliance. Although Kurogiri expresses his doubt about his plans where he uses some of the villains like a pawn, Tomura assures him that he has personal wishes that they eventually succeed.
Meanwhile, Izuku finally defeats his villain who is left unconscious. With the remaining power in his hand, he carries Kouta to the facility. At the facility, Shouta easily rebuffs the attack of Dabi. Although he has pinned Dabi who initially tries to break free, the villain suddenly vanishes.
It was later shown that the Dabi who attacked the professor was merely a clone. The villain who created the clone is named Twice and he was asked by Dabi to make more.
Shouta proceeds to the forest where he meets Izuku. Somehow, Izuku convinces Shouta to take care of Kouta as he heads on to help others. Before he leaves, Shouta asks Izuku to relay a message to Mandalay for everyone to hear through telepathy. Izuku was able to break into the fight of Mandalay against Spinner and Mandalay relays the message to everyone: fighting is now allowed in order to protect themselves from the villains.
The latest announcement by the great professor will definitely open the floodgates to more one-on-one battles. At Narutoforums, Wizzrobevox notes that "it looks like Bakugou is the main target" although it is possible that Mandalay is still getting the impression that there is only one target.
User ShenGao at Manga Helpers posted the upcoming events in the next chapter and it indicates that Izuku was everywhere as he tries to help Mandalay against Spinner and as well as volunteering to find Bakugou. Meanwhile, Tokoyami's shadow is increasingly engulfing Shouji with fatal repercussions.
