Merry's Name is a topic regarding a blonde college student from Touhou Project whose name is allegedly 'difficult' to pronounce, allowing it to be open to reader interpretation. For the English community, most translations have settled on 'Maribel Hearn' unless noted otherwise.

In Changeability of Strange Dream, she reveals that her full name is 'Maeriberī Hān' (マエリベリー・ハーン) for the second track, then mentions that her name had been 'difficult' (にくい, nikui) for Japanese people to pronounce for the fifth track. In Dateless Bar “Old Adam”, her full name was brought up for the first track, then she introduces herself as 'Maeriberī' to the aforementioned bar's patrons for the eight track.

• One popular theory is that her name is 'My Reverie' (マイ・リヴェリー, mai riverī) as the term 'reverie' can mean 'daydream', 'imagination', and serve as an uncommon translation of 'gensō' (幻想).
  • However, this does rely on misjudging ZUN's understanding of foreign names, considering that the PC-98 characters had names like: Ellen, Orange, Elly, Sara, Louise, and so on.
• Another popular theory is that her name is 'Mulberry' (マルベリー, maruberī), as mulberries will turn 'purple' (紫, yukari) when they mature. This obviously satiates the Yukari–Merry theory.
• In the English community, the name 'Maribel' (マリベル, Mariberu) or 'Maribelle' is the popular rough approximation. 'Merryberry' (メリベリー, Meriberī) works, but this sounds like a nickname.
• The 'mae' (マエ) part could be 'mæ', except 'mæ' is pronounced 'may' (メイ, mai) instead. Despite this, one could stubbornly interpret this as 'Mæriberry' or 'Märiberi', if one wanted to.

• The surname of 'Hearn' (ハーン, Han) is the popular consensus and most plausible.
  • Much of the Yukari–Merry connection relies on ZUN hinting he was inspired by Lafcadio Hearn taking Koizumi Yakumo as his legal name, according to a high school lecture from 2005.¹⁾
  • The term 'yakumo' (八雲) has the on-reading of 'hachiun' (ハチウン) or 'hatsuun' (ハツウン), from the Chinese reading 'bāyún', but it has been asserted that 'haun' (ハウン) is valid.
• In 2018, the Touhou Project series collaborated with Line, which somehow resulted in her surname being translated as 'Harness' (ハーネス, hānesu).²⁾ Obviously, nobody takes this seriously.
