so for the past few weeks i have been studying several episode's in fafner exodus, and other episodes with an overlapping KA list with Beyond.

after weeks of research, and narrowing down the suspects, i believe i now have a tangible guess; Futoshi Oonami.

will keep the presume on all of these until i have confirmation.

Update: we have confirmation!! It is Oonami! https://twitter.com/futoshioonami/status/1201089527466450944?s=19
