The opposing team's Spirit Energy 'Retrospective Vision' originally corresponds with Ian's Foresight View. As a leader, no one would object, and it also allows Ian to focus more on the technical aspects.
With that thought, Ian brought Elan, using the Heart of Terra to examine the Spirit Energy structure of the other party.
This is a very, very complex Spirit Energy, the requirements are extremely complex, even slightly more complex than 'Holy Light'. Ian keenly noticed that Elan's desire to awaken Spirit Energy back then was not simply to know Ian's situation, but to understand 'what exactly happened'.
The awakening of the Retrospective Vision must require an extremely powerful curiosity, a strong desire for a certain target, and a pure goodwill — because it is goodwill, it can get a response from the past.
This is really rare for Terra nowadays.
Wanting to replicate the Retrospective Vision is quite challenging.
"No wonder I installed this Spirit Energy in the 'Guiding Star'."
