Best hanime is sponjebobs squarepants
But seriously try OPM. It was the first one I watched
I don’t think you know what a Hanime is..OPM is not one 😭😭 although Saitama does look like Johnny Sins.
For beginners I recommend:
Isekai Harem Monogatari
Kanpeki no Ojou-sama ga Watakushi
Youkoso! Sukebe Elf no Mori e
Ochi Mono RPG Seikishi Luvylias
Tensei Kendo no Harem Colosseum
JK Bitch ni Shiboraretai
Kyonyuu Princess Saimin
Knight of Erin
What do you think?
