"frivolous writing"
Tentenō, the gesaku (戯作) writer Takabatake Ransen, adds 戯記 rather than the usual 記 (ki) or 誌 (shi) after his name. He also signs TNS-781, TNS-913b, and TNS-1036b this way -- reminiscent of 戯筆 (girefude) or "frivolous brushing" in Yoshiiku's signature on the frontispiece of Kanagaki Robun's Aguranabe.
Tentendō, as a 戯作者 (gesakusha) or "writer of fivolous works", in writing 戯筆, appears to be punning "geki" (劇) " and works, and . writer of 戯作戯記

The Kishōza (喜昇座), which opened in 1873 in Hisamatsuchō in Nihonbashi, was remodeled and reopened as Hisamatsuza in 1879. After a 1880 fire it was rebuilt and reopened as Chitoseza in 1885. Destroyed by fire again in 1890, it was rebuilt as Meijiza in 1893. Several generations, earthquakes, wars, and buildings later, the Meijiza continues to be a major Tokyo theater.
Writer of minor stories reflects 小説の作者. Though there are no furigana, the graphs 小説 would most likely have been marked to be read せうせつ (seusetsu), though しょうせつ (shōsetsu), the reading today, would also have been possible at the time.
