It soon reaches the point where there are no yukkuri that is even less easy than it, and the lowered paste function meant it is at death's doorstep. As it cannot be raised more through trauma, it can be little more than nourishment for new Maricha.Thus concluded,Research and Investigation Report on Consumer-oriented Scum-raising MethodTherefore, for the esteemed "Scum Yukkuri Salvation Association", I respectfully suggest changing the current policy of "love thy scum" and search for a new direction.Despite the hope of elevating scum yukkuri from its current predicament, the inability to contribute to such a noble goal is very unfortunate.The current status of paste-for-brain scum yukkuri in human society is worthless beyond being food. They're considered troublesome by wild clans, and immediately purged as stray gutter trash. In such a hostile environment, it is difficult for them to experience happiness.This research is unlikely to achieve more than that. As of now, the conclusion can be summarised as "it's difficult to raise scum yukkuri".After all, this way of raising yukkuri is focused on "saving one's hassle of raising a scum yukkuri", ignoring the health of yukkuri entirely. As such, this result is only predictable.Because of that, the life expectancy of yukkuri raised by the trauma method is barely more than 1 year, a significant reduction from the usual 6-8 years for pet yukkuri's.Due to repeated manifestation of anti-yukkuritis, its core paste shrivelled up, its viscosity increased as well. Because of the reduction in rate of metabolism, its skin became fragile, its braid fell off, and it lost its sight as well.
