| Description | A section of a mech’s bionic spinal column. Can be used for the Ascension of Lightning characters. | |
| Story | The most important central component of the mech that was built in imitation of the borisin. Though the body that nurtured it no longer has even a sliver of life left, this component still maintains the “Slaughter Algorithm” inherited from primordial days and buried deep within its genes. “While you see a monster that can never be killed, I see infinite parts to salvage. That’s the difference in perspective.” |

better E1S0 or E0S1 Cyrene for E0S1 Evernight + E0S5 DDD Tribbie/RMC TB + E0S0 Hyacine?
