While Edward walked, he created an ice cube and pierced it easily with his index finger, but didn't get the desired result, saying, "It's very irritating not being able to use implosion with it. It would be so easy to shut everyone up and make them listen to me."
"I would say that's too cruel even for me... But curiosity overrides my morality, so..." Litty paused in her speech, flying in front of Edward's face with her right eye closed and arms crossed, and continued, "The ice seal works on non-human beings, so implosion shouldn't work either, right?"
'Why is she closing her eye?' Edward thought, almost forgetting what Litty had said, but quickly recalling it, he replied as the ice cube began to crack and explode, "I can't directly interfere with the mana flow of other living beings, maybe not even the dead... The magic in this world is simpler, but there are some annoying aspects to deal with."
