Agate used to be an explorer of the flavor horizon who wanted nothing more than cooking.
Liu Pleiaxing and Jin Ling used to hate agate that took too much care from their mother, until one day they discovered that agate was different from them.
Agate's former name was Soma Yukihira.
Yes, as a single-minded explorer of taste, he never expected that his sense of taste would fail.
