As such, the experience of "Angst vor Dasein" ("anxiety in the face of existence") generated by recognizing mortality impels Kamina to reevaluate his core assumptions and relinquish the inauthentic values of the they-self, retaining only the genuine, personally significant assumptions of the I-self (Heidegger 57-58).
Even so, due to cognitive conservatism--the resistance to change fundamental core assumptions such as personal invulnerability--we latch onto hope as Simon does when Kamina revives himself in time to defeat the enemy.
He resiliently invents the unnamed multi-drill attack that prefigures Simon's later, inadequate Giga Drill Maximum attack, and the Giga Drill Break, which leads to victory and becomes an enduring signifier of Kamina and his core assumptions.
In fact, Simon's irises are a central visual signifier of trauma and mirror their appearance when Kamina was fatally attacked: three trembling concentric circles.
Following Kamina's death, Simon chants that he must become tough enough for both himself and Kamina, as though attempting to retroactively save Kamina's life.
The reflexive image underscores the radical difference between Simon and Kamina and the folly of adopting another's identity to bypass traumatic stress.
Simon's eyes reacquire their traumatized appearance whenever mention or memory of Kamina intrudes.
Notably, although images of Kamina explicitly show that "this man" is Kamina, Simon does not verbally confirm this, implying that doing so is still too painful.
The closest Simon comes to acknowledging this is with Nia, but the fact that he only does so while drilling numerous Kamina statues further suggests he can only confront the memory under the illusion of Kamina's presence.
However, the entire sequence is couched in reflexive imagery associated with Kamina and his assumptive world.
Simon pulls down his goggles in a gesture coopting the culture of cool associated with Kamina donning his shades.
Similarly, his multi-drill Giga Drill Maximum attack, an evolved version of an attack Kamina invented and successfully used, also fails to stop the enemy (Gurren Lagann, Ep.
