God, I don't really ship things in anime much anymore because it always lead to disappointment (Rem was better girl lmao) from what I can remember
-SenGen from Dr.Stone
-Beatrice and Battler from Umineko no Naku Koro Ni (I like the insanity of the series and the stuff between them in the VN)

Dunno about the last one. I like DKBK and DkBkTk but the kiddos in that fandom will cancel my ass lmao. The two Mikis in Devilman Crybaby. Naruto/Shikamaru would've been a favorite if the build up of Shikamaru wanting to help Naruto be Hokage and all the childhood flashbacks of him being the only one that treated him nicely happened earlier in the series, ngl.
