Fate/stay night, Soul Buster Recommendations
Soul Buster is definitely a shorter and less detailed alternative of Fate/Stay night. The start off of both anime are different, but the basic concept of the two involves teenagers playing a game and putting their life on the line for the card that they picked from their dream world. Essentially, there are other players who also chose a card and they hunt each other for the card they have to achieve whatever goal is placed for them.
Heroes of old get summoned to fight each other for their masters to achieve a goal.
Well even if I only saw one episode I think I can already try su recommend something. The first episode reminded me of fate/stay a lot.
Both main characters are confused of what is happening and somehow summons a female who saves them and both female characters seem to be strong and good with swords.
