The Anime Lad
Graduate researchers Himuro and Yukimura suspect they are in love. Suspicion is insufficient, so they begin designing experiments to establish a measurable definition. Their labmates become observers, assistants, and unwilling controls. Basic romantic communication might be much faster, but it would produce less publishable data.
Super Eyepatch Fox
Himuro tells Yukimura she may love him. As scientists, they refuse to leave the claim untested. Their university lab becomes a testing ground for heart-rate measurements, controlled situations, and increasingly elaborate definitions. The comedy comes from using formal methods to avoid one painfully obvious human conversation.
Gigguku
A normal romance would let two people blush and move on. These two demand data. Himuro and Yukimura recruit their labmates, quantify reactions, and turn simple closeness into an experimental protocol. The formulas are playful rather than rigorous, but the emotional logic is perfect. Analysis becomes their shared flirting language and their favorite hiding place.
Father's Basement
Anyone expecting serious research practice should lower the significance threshold immediately. The experiments are comedy props. Still, the premise understands a recognizable academic reflex. Himuro and Yukimura would rather operationalize love than risk an unmeasured answer, so their mutual attraction expands into lab meetings where everyone else can see the conclusion they keep testing around.
