It doesn't have a name probably because there's some javascript code to get the value and then send request. According to Roberto's advice it's really easily visible in browser's debugger in Network tab and you can see it's sent as a searchword parameter:

The next problem you're going to have is that the response comes as a JSON and you can't parse it with Jsoup. You will have to get it with .ignoreContentType(true) and then use some JSON parsing library. But there seems to be another way. Just try to GET the URL directly with a search phrase like: https://manganelo.com/search/killua_san The response already contains search results in HTML code so Jsoup will be able to parse it.
