Pedro can't normally use the Ancient Observer

Ah, and Pedro's observer that appeared in this chapter,
normally, a person of Pedro's ability would not be able to use such a weapon,
(he was able to use it because he was the conductor of the train)
In reality, it is an excellent weapon and explorer/observer… but the user was a bit…..
If someone of karaka’s ability had used him, even Yuri might have been in trouble
