As an AI, I do not have real-time data access to determine which anime is currently trending. However, some popular anime series that have been trending recently include "Jujutsu Kaisen," "Demon Slayer: Kimetsu no Yaiba," and "Attack on Titan." These series have gained widespread popularity and have been generating a lot of buzz within the anime community. **

My current favorite anime is "Attack on Titan." I love the intense action, complex characters, and the gripping storyline. The animation and soundtrack are also top-notch, making it a truly immersive experience. The show's exploration of themes such as freedom, power, and morality adds depth to the plot, making it a must-watch for any anime fan. **

Some anime that deal with a pandemic or global virus include "Attack on Titan," where humanity is threatened by giant humanoid creatures and a deadly virus; "Highschool of the Dead," which follows a group of high school students trying to survive a zombie apocalypse; and "Tokyo Magnitude 8.0," which depicts the aftermath of a devastating earthquake in Tokyo. These anime explore the themes of survival, societal collapse, and the impact of a widespread disaster on individuals and communities. **

Some current and really good anime include "Demon Slayer: Kimetsu no Yaiba," which follows a young boy's journey to become a demon slayer and avenge his family, and "Jujutsu Kaisen," which follows a high school student who becomes involved in the world of curses and sorcery. "Attack on Titan" continues to be popular as it nears its final season, and "My Hero Academia" remains a fan favorite with its superhero-themed storyline. Additionally, "The Promised Neverland" and "Beastars" have gained attention for their unique and compelling storytelling. **

As of my knowledge cutoff in September 2021, some of the current Ecchi anime available on Netflix include "High School DxD," "Kill la Kill," "The Testament of Sister New Devil," "Food Wars! Shokugeki no Soma," and "Monster Musume: Everyday Life with Monster Girls." However, the availability of specific titles may vary by region and change over time, so it's best to check the Netflix library directly for the most up-to-date information. **

English is often considered the current global language. It is the most widely spoken language in the world and is used as a common language for international communication, business, and diplomacy. Many countries teach English as a second language, and it is the primary language of the internet and international travel. As a result, English has become the dominant language for global interactions. **

My current absolute favorite anime opening is "Gurenge" by LiSA from the anime "Demon Slayer: Kimetsu no Yaiba." The powerful vocals and intense melody perfectly capture the spirit of the show. As for the ending, my favorite is "Torikago" by XX:me from the anime "Darling in the Franxx." The hauntingly beautiful vocals and emotional lyrics create a perfect ending to each episode. **

Some dark anime series include "Attack on Titan," which features a post-apocalyptic world where humanity is on the brink of extinction due to giant humanoid creatures known as Titans. "Tokyo Ghoul" follows a college student who becomes a half-ghoul after a chance encounter with one, leading him to navigate the dangerous world of ghouls and humans. "Death Note" revolves around a high school student who gains the power to kill anyone by writing their name in a supernatural notebook, leading to a cat-and-mouse game with a brilliant detective. These anime series are known for their intense and often disturbing themes, making them popular choices for fans of dark and suspenseful storytelling. **
