Trishanku's heaven revisited

Moonless nights in the Bamboo Forest of the Lost were usually quiet, this one was destined to be so also, were it not for two new arrivals. Outsiders - entities foreign to Gensokyo, careening through the bamboo fields, locked in intense combat with one another. Fingers upon two pairs of humanoid arms interlocked and foreheads met in unflinching zeal, uncaring, unfettered for collateral damage sustained to their environs, though both were close-to-yokai enough that they would stop short of endangering an obvious bystander.

Unfortunately the weather had turned unfavorable for combat; a harsh thunderstorm had come over the forest rendering unaided visibility extremely poor, thus the two outsiders were locked in a grapple as they flew through thickets of bamboo; one a massive, monstrous drider-like female, the other an unusual fairy-sized redhead.

Thunder and rain roaring above their combined screams of fury amidst intense battle, they slammed into the gated fence of Eientei with a sickening, organic wet CRUNCH! The smaller of the two losing her left arm as it tore off from the shoulder, a metal bar tearing through her armpit. The larger and arguably more monstrous of the two, also a redhead lost its hind tripod-arranged armatures - a stable leg and two overarching arms behind and above the head. Neither of them reacted by howling in pain as one might expect, they were both focused on each other to notice the environment with great awareness.

Separating as they came to a jarring halt, both overbalancing and flung off their feet as they impacted the outer wall of the clinic proper, not slamming through it as their momentum carried them through a half-dozen bamboo thickets and the surrounding fence. Both temporarily stunned from the impact, granting a needed reprieve and halt to the raging storm. The larger was the first to recover; forward legs dragging itself away from the local structure, unwilling to involve local incipients as it despised the necessity in grievous slaughter, as well as a sharp intent on repairing itself and proving the other wrong in their heated fight; an argument that had merely lasted the prior 2 minutes.

The other, the alien humanlike brained female had innumerable capabilities, though offensive capabilities weren't locally optimized; remnants of a strategy 5x9^10 years old. A 'Terminal Protocol'. A filter, a command, criteria to judge whole species by. Not an individual, nor even a construct born of another species, as was Amon's enemy.

As the smaller of the two - Lana, lay in a puddle of her own blood, she ran a quick checklist of weaponry systems that had been used and rendered inoperable since they had begun their fight a few-dozen kilometers west of their current abode.

All four tiers registered inoperable, greyed-out, either destroyed or power incapable of activating. She just had her two legs, head and one arm remaining to beat the everloving life out of her tormentor.
