Does the Vein Council only have Gegil as an enemy in the Magic Academy?
You're far too naive.
The Vein Council has enemies in every single organization within the Magic Academy. If you were to list them all, none would be spared. That includes its nominal superior, the Magic Academy Student Union.
Yes, even the Student Union, which shares administrative responsibilities, and is technically its superior, counts as one of its adversaries.
The difference is, other people who detest the Vein Council aren't as radical as Gegil.
History shows, do people hate their enemies the most? No, they hate traitors. Normally, when two sides face off, most people's first instinct is to take down the traitor before the enemy.
And the Vein Council is widely regarded as the traitor among students. Even though they're just dutifully carrying out their responsibilities of maintaining order in the Magic Academy, it doesn't stop the majority of students from despising them.
