Topic: Help anime fans. I forgot the names of some anime I watched from my past

When I was young, I remember watching some anime on my TV with my brother. When I was on senior high school, I joined the japanese language extra curriculum. To my surprise, the extra curriculum consist of nothing but watching anime while learning Japanese from said anime. It was a unique experience during my senior high school. Anyway, I want to know the titles of the animes I watched from both of these past moments. I managed to find out the name of some anime I watched in the past. However, there are still some anime I have no idea what its name is but I know I watched in the past. Here is the description:

1. There is a bunch of nude joke in this anime. I remember a specific shot with three men with their rear exposed. There is a scene where the male protagonist gives his friend (who is a girl, possibly a girlfriend) a souvenir. She thanks him, the protagonist leaves the scene, and the girl call the protagonist baka in her thought. This anime might have something to do with swimming or diving.

2. This anime is about a group of rebel who assassinates corrupt people in a city. In an early episode, protagonist go to the city in hopes of getting a job. However, he end up becoming homeless. A princess offer him a home. An assassin want to kill the princess but the protagonist defend the princess from the assassin. The protagonist then found out that his friends are killed (probably by the princess). Angry, the protagonist killed the princess who plotted to poison the protagonist. Most episode (or is it every episode?) is titled: "Kill the [blank]"

3. People got sucked into an RPG world. This anime has a big guy who is a knight, someone who look male then at one point somehow turn into a loli wizard, a vine spell that help the good guys, and an antagonist who loves killing weak people. People can respawn after death in this RPG world.

4. This might be from the same anime on number 3. I remember two pickaxe wielding monsters kill a hero's friend. The hero is heartbroken and he is also slain later. They then respawn.

5. The protagonist is a magical girl who at one point visit a floating island with some weird creatures on it.

6. This anime might not even be real because this is just a very faint memory from my brain. I remember there
is like a facility (probably a research facility) surrounded by harsh snowstorm. You can see the outside world from the facility through glass. That's it.

7. This might be from the fate series but I'm still kind of doubtful about this. In a dystopian Tokyo (I think), a male protagonist has a female servant. The servant can talk to her master (which is the protagonist). The protagonist fight using his servant. I remember the protagonist's servant fight a young girl's servant.

8. This anime is about a man and a baby. The baby cause trouble and hijinx ensues, I think. I remember a creature keep attempting to put a certain food on a girl's meal despite the girl not wanting that food to be in her meal. At one point, the girl punch the creature so hard that the creature flew through the sky like a comet. A child witness the creature flying through the air and he then said that it (the creature in reality) is a beautiful star or comet.

9. The main three characters consist of a boy, a girl, and a boy who can't speak with his mouth. The boy who can't speak instead uses a laptop which can speak anything that the man types. One episode has a duo (which reminds me of Jessie and James from Pokemon) challenging about quizes to the trio. At the end of the episode, the main boy ended up joining the duo in challenging other people to quizzes. There is some type of unique battle system and it has something to do with how well you do in school subjects such as math.

10. A boy bullies a girl who can't speak or hear. He grow up and he regret his action in his past. He attempt to befriend the girl from the past. Some drama happen.

11. Can't remember but the first few episodes names all start with the same letter. The first letter of the names of the episodes are larger (I think). One of the earliest episode names might have something to do with cats.

12. This anime has people turning into cats. The cats has something to do with spirits or something like that.

If you know the name of the anime based on these description, please let me know. Also, can you recommend the animes I described above?

Number ten is "A Silent Voice" for sure. Twelve Might be "the Cat Returns" from studio Ghibli. Not sure about the rest, some descriptions are just too vague to parse anything from.

Oh I know the third one because I saw a clip of it a long time ago but I can't for the life of me remember what it was called. Maybe it was called Suikoden or something?

EDIT: It also sounds a lot like Sword Art Online (though the respawning thing is very anti-thetical to that show so maybe not).

@NoName404 try Googling those descriptions, Google is pretty good at finding movies through very vague descriptions.

@Kermit1 All right. I'll try finding the name of these animes with the power of Google.

I tried using the power of google. I didn't found the result I needed. However, I found the forum for myanimelist.net. I'll try asking there instead. Maybe they know anime a lot more.

Maybe #8 is Beelzebub?

I've never watched it, but it seems to prominently feature an infant looking character (with green hair) based on the images I've seen.

@Royalblues These names are ridiculous. Not as bad as the titles that literally tell you what the show is (I believe there was one that went along the lines of 'Why Do I Have Super Powers In Another Life?' which is just scratching the surface honestly) but how do you even begin to pronounce it.

@NoName404 Yeah, ten is without a doubt A Silent Voice. Can't help you with the rest though, sorry.
