The product we'd like to introduce to you today is called... "Puffing Reimu"!
Made to compete with the crying yukkuris developed by other companies, this product--! She's actually puffing up all the time!
Her mouth is shut, so she never cries or makes a fuss! And she's reasonably priced!!
...However, this yukkuri is a little difficult to care for, so she's a yukkuri suited for top breeders!!
The first problem is that regardless of her own intentions, she's continuously issuing a threat, so she constantly causes displeasure to the yukkuris around her.
Depending on conditions, this can lead to circumstances in which she is killed by her own kind.
Another thing is that since she's continuously puffing, she can't take food in through her mouth!
As in the illustration on the right, she can only make little "Pwufff, pwufff" groaning sounds. (getting pissed off)
But it's okay! Her lower mouth has evolved in conjunction! She can't take food for herself, so please shoot some sugar water up her anyaru!
What's that? "Sugar water? I can't use anything else?" you ask? Tabasco sauce and chili paste and the like are okay, too!
Since she's puffing up, her skin(?) has high resilience--even if you hit her with a ruler, she won't leak bean paste right away! She's a little sandbag! But if you escalate things too much...
