TCP J05384230+7051377: possible period bouncer
Itoh-san reported the observations. The possible period of the early superhump is ~0.065 d, and this value implies that this object is a period bouncer. The last night's data shows likely growing (stage A) superhumps. The dense observations in this period will reveal whether this object is indeed a period bouncer.

TCP J05384230+7051377: new WZ Sge-type dwarf nova
We posted our spectroscopic follow-up result of TCP J05384230+7051377 to ATel. ATel #17485: Spectroscopic confirmation of TCP J05384230+7051377 as a WZ Sge-type dwarf nova https://www.astronomerstelegram.org/?read=17485
We concluded that this object is a new WZ Sge-type dwarf nova because Hα has a narrow emission core and its spectrum shows a blue continuum with the Balmer and HeI absorption lines.
Also, we estimated this object as p ~ 0.06d from Itoh-san's data. However p ~ 0.06d is a weak signal, so further observation will provide a more accurate estimate of the period.
