Generally, the surname should be used but if their given name, nickname, or alias is what they are better known by, we opt to use that instead.

Such as Yumitsu Tomoe, she's referred to as Grave Robber in her article. But Hajime's case is more like Kimi's or Roma's, it would take most a moment if they read "Nishino" or "Hoito," same with "Hazuki."
