Marine Headquarters' Admiral Candidate, Vice Admiral Momousagi, had been detained by the World Government.
Momousagi's strength truly lived up to her status as an Admiral Candidate. She had already been powerful, an unstoppable swordsman who specialized in offense. After Su Yu taught her swordsmanship, her strength had increased at an absurd rate, even though she had not even grasped the basics of his swordsmanship after a year. Put it this way: even Aokiji wearing his Cloth could only fight her to a standstill.
That made arresting Momousagi head-on far too difficult, with too many uncertainties, so the World Government resorted to underhanded tactics.
First, they tricked Momousagi into coming to the Holy Land Mary Geoise, then spiked her tea.
The crucial point was that they had not used poison or sedatives. After all, a swordsman's Observation Haki warnings were no joke. What they added was something good-a Paramecia Devil Fruit!
By the time Momousagi drank the tea and realized something was wrong, it was already too late. A speed-specialist CP0 agent had already snapped Seastone Handcuffs onto her wrists.
Just like that, the operation to arrest Momousagi was a resounding success!
It had happened so suddenly that by the time Sengoku and the others found out, the deed was done. Sengoku protested repeatedly, to no avail. He wanted to go to Mary Geoise to see the Five Elders, but they refused to receive him. That made one thing clear: unless the Marines openly rebelled, they had no way to get Momousagi back!
Why had the World Government suddenly moved against the Marines? Because Vice Admiral Momousagi was suspected of having an improper relationship with the world's most heinous criminal, Su Yu, so the government intended to publicly execute her outright!
Not long before, Su Yu had openly attacked and killed
