As the Blacktongues besieged UA, Pan and the UA staff mounted a defense to buy the students time to reach the Sports Festival Stadium. The Heroes soon set up a defensive position at the cafeteria. As the Blacktongues began to break down the doors, Pan rallied the Pro Heroes. 

Pan: Heroes, this is where we make our stand! The Blacktongues will seek to kill us all! We must hold the line no matter the costs! 

Aizawa: Our students are counting on us! We can't let them pass!

Present Mic: This oughta be interesting!

The Pro Heroes prepared for battle as the Blacktongues began to break down the door. To even the odds, Pan used his magic to empower his allies. They would stronger and faster than normal. 

Pan: Our enemies will not relent! Neither shall we! 

In that moment, the Blacktongues broke through the doors to the cafeteria. As they did, a horde of Blacktongues and Tartarus Fiends began pouring into the cafeteria. Pan led the charge as the Pro Heroes held the line against the Blacktongues. In an attempt to thin the herd, Midnight tore off pieces of her clothing to activate her Somnambulist Quirk. Empowered by Pan, Midnight secretes a large cloud of sleep inducing cloud which filled the room. 

Midnight: This....is exhilarating! 

Pan: Do not fret, my heroic friends! Midnight's gas will have no effect on us! My magic shall see to that!

As Midnight's Quirk filled the cafeteria, many of the Tartarus Fiends fell unconscious due to the smoke. However, most of the Blacktongues remained unaffected. 

Blacktongue Assassin: Kill them all! Send them all to the paradise of Tartarus!

Present Mic then used his Voice Quirk to unleash a wave of sound which incapacitated a group of Tartarus Fiends and a few stray Blacktongues. As the battle goes on, Pan and the Pro Heroes hold the line. 

Pan: Do not let up, my friends! 

As Aizawa takes down a Tartarus Fiend, he finds himself surrounded by four Blacktongue Assassins. 

Blacktongue: Give up, Hero! You and your students will fall before the might of the Blacktongues!

Aizawa: I don't intend to let a death worshipping cult lay a finger on my students! If you want my students, you'll have to go through me!

Aizawa then attacks the Blacktongues, taking them down with ease. As the battle progresses, Pan becomes concerned at how easy the battle was going. What Pan didn't know was that the force attacking Pan and the Pro Heroes were simply a diversion. Meanwhile, the Argonauts along with Talia guided the students to the Sports Festival Stadium. As the students went inside, Shoji remained. 

Shoji: I'm coming with you. 

Talia: No, Mezo. It's not safe. The Blacktongues are unlike anything you've ever faced. 

Shoji: I don't like leaving you alone, Talia!

Midoriya: She won't be alone, Shoji. We'll keep watch over her. 

Talia could tell that Shoji was worried about her. However, she didn't want to put him in danger. She placed her hand on Shoji's face.

Talia: I'll be fine, Mezo. 

Shoji took Talia's hand and held it tightly. Shoji sighs as he enters the stadium. As the Argonauts were left alone, Talia takes a deep breath. 

Talia: By now, the Blacktongues will have breeched the school. Pan and the other teachers will be fending them off. We need to help them. 

Bakugo: Just show me where these bastards are and I'll blow all of them to Hell! 

As Bakugo says that, Jiro senses something wrong. She feels something coming towards them. Using the Sight Of Hermes, she looks around to see what was coming. To her shock and horror, Jiro saw Hep'naje towering over Yaoyorozu. The manticore was snarling at Yaoyorozu, ready to ambush Yaoyorozu with it's stinger.

Jiro: Momo! Behind you! 

Jiro pulled Yaoyorozu out of the way as Hep'naje became visible. Without hesitation, Bakugo unleashes a powerful explosion on Hep'naje. 

Bakugo: TAKE THAT YOU UGLY FUCKING ANIMAL! 

As the smoke cleared, Hep'naje was gone. Everyone was shocked at what they had just seen. 

Kirishima: What was that thing?!

Talia: That....that looked like a manticore. 

Midoriya: Looks like the Blacktongues aren't pulling any punches. 

???: My beautiful Hep'naje is the least of your worries, human!

As the voice calls out, Nessus rushes at the Argonauts and swings his battle axe. The Argonauts were able to dodge the Centaur's attack. Soon enough, Docon and Phaedon arrived. 

Midoriya: Who are these guys?!

Docon: I am Docon! Champion of Ionia! Champion of Hecate! And you have stepped into my ring!

Phaedon: These are the ones calling themselves the Argonauts? How amusing!

Bakugo: Keep fucking talking, pretty boy! I'm about to blow you and your friends straight back to whatever hellhole you crawled out of!

Talia could sense that something was off about these three. It was clear that they came from Tartarus. However, they were not mindless beasts. They still retained their intelligence. 

Docon: We know you serve the Satyr. We know you are his students. 

Phaedon: However, we feel that you all are....easily swayed. You've been blinded to truth and reason. 

Yaoyorozu: No one with reason would ever serve the Blacktongues!

Phaedon: I see you're just as stubborn and foolish as the last Argonauts. No amount of debate will serve us here. Allow us to show you the truth. 

Nessus: Hep'naje! Let us show these children what true power is!

In that moment, the Argonauts were face to face with the generals of Hecate. An epic fight would soon follow as the Blacktongue invasion of UA continued.
