So i have come across a few animes that i find very underrated and barely anyone knows them. Mainly BloodLad, Toilet-Bound Hanako-Kun, Charlotte, and Love Stage. All of which i absolutely loved to watch, however they are not as popular as one like SAO, BNHA/MHA, and more, considering if you have even heard of anime you know what those stand for. A lot of them also only have one season currently if that. So, im going to give a summery of each, and if it sounds interesting to you, i implore you to watch.
BloodLad- Alright, so you have Staz, the main character who is a vampire and rules over his territory in the demon world. He is also a hardcore otaku and obsessed with humans and their creations (like video games, manga, anime, you get the gist). So one day there is a human girl who stumbles into the demon world into Staz's territory. And out of all things, in the first episode she is eaten by a plant and dies. However, she becomes a ghost and Staz promises to help her and revive her basically. Definitely and interesting anime though.
Toilet-Bound Hanako-Kun- The main character here is Yashiro Nene, and in the beggining she has a crush on a boy from her school, so she goes to a wish-granting spirit that resides, for some odd reason, in the old school building's bathroom. That apparition (ghost basically) would be Hanako, one of the Seven Wonders (seven apparitions) of the school. Like any other protaginist, she does the one thing he warned her not to do and Hanako has to save her and she becomes his assistant. I 100% love this anime. It is really cute and colorful and just a bit of darkness here and there.
Charlotte- Oof, where to start. So you have the main character, Yuu, and he has the ability to possess people for 5 seconds at a time. He usually uses the ability for things like cheating or payback and other things he probably shouldnt do. Then a girl named Nao, who is part of another school sees him and makes him join her school which is for people like him who have special abilities or are likely to have one. The reason the school is there is so that they dont get caught and expirmented on. Yuu joins the student council with Nao and Jojiro to help find other kids with abilities and either bring them to school or threaten them if they use their powers again. This anime is a really good one, the art is fantastic and the plot is absolutely amazing (I LOVE THE WRITER). Fair warning, it does get sad however it leads to some very good character development.
Love Stage- BL. I am not gonna be good at explaining this, so here is the official desc- Izumi was born in a family of celebrities. His father is a singer, his mother an artist, his older brother the lead vocalist for the popular band Crashers. Izumi himself, however, is just a nerdy college student. He loves the manga "Magical Girl Lala Lulu" and dreams of becoming a manga writer himself. One day he is roped into filming a commercial where he wears a dress. Another actor on the set, Ryoma Ichijo, mistakes him for a woman and falls in love at first sight. As it turns out, though, they met ten years in the past. And Ryoma feelings don't change when he finds out Izumi is a boy. (End of desc). This show is pretty good and is one of the few BLs on Hulu. It does have quite a bit of fanservice which i dont particularly like, however the plot otherwise is cute. Very good art, and i will have to search the artist for their other works.
