According to some 'Kamiwaza Wanda' fans on twitter, Liftmin is in love with Hasamin, another Promin belonging to the Punpun attribute.
Liftmin's Kamiwaza ability is to lift up heavy objects. As a Bugmin, he can make a forklift run away and sometimes uses it to kidnap other Promins.
In the series
Liftmin first appeared as a Bugmin in episode 9 when the Bug Bites demanded him to use a forklift to kidnap the Promins that Yuto has so far except for Turbomin, Gauzemin, Tonkmin, Railmin and Hasamin.
Bug-Liftmin later appeared in episode 10 when Yuto captures and debugs him as well as recapturing and debugging the other rebugged Bugmins.
Liftmin was first summoned in episode 12 in order to pick up the heavy log with help from the other Promins.
In episode 40, Liftmin was summoned along with Tonkmin by Yuto to help him deal with Bug-Tengumin. However, after he lifts up a heavy stack of cars as he shows how strong he is, Liftmin was effected by Bug-Tengumin's Bugwaza ability.
Along with Sukemin, Liftmin was kidnapped by Bug-Katasumin in episode 43. He was rebugged and was forced to stop Chakkamin, Stopmin, Hanshamin, Cafemin, Yajiromin and Dorirumin by kidnapping them with a forklift. Bug-Liftmin was recaptured and debugged along with the rest of the remaining Bugmins in episode 45.
Liftmin made a camero appearance in episode 47 when he was carrying a stack of pipes for Wanda's spaceship.
