While he and his partner Yuki are getting their music careers rolling again (including having performed at Eostre again recently), Momo's primary jobs since arriving over a year ago now are in radio and modelling! He mostly does morning radio shows and does a lot of interviews with local personalities, but he does also do a late-night show on Wednesdays where he sometimes talks about spicier topics - either way, there's a high chance a character who listens to the radio with some regularity would've heard him, or even if they frequent a bar or cafe or something where the radio runs in the background. Regardless of what time he's on, it's pretty obvious he's a longstanding professional at this given how well he handles guests and keeps the mood going. As far as modelling goes, he usually works for either individual designers/tailors or occasionally department stores, so feel free to handwave having seen him in a department store magazine ad/catalogue, in a tailor/designer's books of custom clothing options they can have made to order, or occasionally in in-store adverts for other places such as cafes, clubs and very occasionally some of the more toned-down red light district stores where they just want him to look sexy next to a product or something (usually featuring far more skintight clothes than he usually wears, in which people can realise he's far more muscular than one might expect).
