Reword this.

Imagine shipping Giyu and Nezuko

Or incestous ships like Tanjiro x Nezuko, Genya x Sanemi, Michikatsu/Kokushibo x Yoriichi, and Muichiro x Yuichiro

Think about pairing Giyu with Nezuko.

Consider familial relationships like Tanjiro x Nezuko, Genya x Sanemi, Michikatsu/Kokushibo x Yoriichi, and Muichiro x Yuichiro.

No more of a slightly, and I mean EXTREMELY SLIGHTLY, disgusted tone.

Incomprehensibly fathom the notion of shipping Giyu and Nezuko.

Contemplate the most abhorrent form of ships, such as Tanjiro x Nezuko, Genya x Sanemi, Michikatsu/Kokushibo x Yoriichi, and Muichiro x Yuichiro.

Here is a reworded version:

Consider the concept of "shipping" Giyu and Nezuko together, or contemplating incestuous relationships such as Tanjiro x Nezuko, Genya x Sanemi, Michikatsu/Kokushibo x Yoriichi, and Muichiro x Yuichiro.
