Why would you want anything more ? Yukkuri's wail of suffering will make crying child laughs and make comatose person awake cured.
Anyway, the yukkuri shooting game in festival are diminishing this year. It's the same thing as how yukkuri can't be used to measure your skill, when an Abyuser use the cork gun, it's as if the cork bullet has homing function that will hit all the time as long as the target is yukkuri. Bad business
