"Endure it, boy."
Aleph urged as he watched Eren's agonized form.
"The pain will be overwhelming for now. However, in due time, it will allow you to claim what was once mine. With this act, I have designated you as my true heir.
I shall also task you with completing what I left unfinished, or what lay beyond my own capacity," Aleph spoke to Eren with a steady tone even as he grappled with the excruciating pain.
Eren's perception of Aleph gradually blurred, his image dissolving into indistinctness, his voice seemingly faded as if emanating from a distant room.
"Um… that's about it. Oh, and please, take care of my sister, would you? She has her own challenges to confront. Extend her a helping hand if you're able," were Aleph's final words to Eren before his consciousness dissolved into nothingness, and he succumbed to unconsciousness.
