Cecil's observation perspective is unique twist—having the story told from the prince's viewpoint as he watches his fiancée's villainess attempts subverts typical otome game isekai. Yusuke Kobayashi voicing bored prince is perfect; his ability to convey subtle amusement suits a prince who finds life mundane until Bertia's antics. Failed villainess attempts sound hilarious—Bertia trying and failing to be evil while Cecil observes creates natural comedy. Prince watching fiancée be "evil" is comedy gold; the contrast between her villainous aspirations and constant failures promises entertaining misunderstandings.

The upcoming TV anime based on the fantasy romance isekai light novel series An Observation Log of My Fiancée Who Calls Herself a Villainess published a new character trailer today focusing on Cecil (voiced by Yusuke Kobayashi), the crown prince who takes an interest in his betrothed's antics when she declares herself the antagonist of an otome game. The series will broadcast in Japan in 2026.

The Story

Hanashi Media describes the story:

Exceptionally gifted to his own detriment, Prince Cecil had always found life effortlessly mundane. One ordinary day, his life took an unexpected turn when he became engaged to Miss Bertia, the Chancellor's daughter. This engagement, however, was anything but typical.

"Prince Cecil! I must confess – I am the villain of this story!" Bertia's declaration was startling. She claimed to have memories of her former life, where she had been the antagonist in an "Otome game". Her lofty ambition was to excel as a villainess and thus have her engagement annulled. However, despite her plans for various misdeeds, her attempts have always been unsuccessful.

Is his fiancée, who aspires to master villainous finesse, simply misguided in her endeavours?
