Chapter 1
| Hitori first appears in Chapter 1.II; after setting an alert for it on Sumire's phone, a news update reports that Eito Hojo, the abusive ex-boyfriend of Yumi Hitori, has been released from prison on good behaviour, Sumire makes a hasty exit after the shock forces Hitori to front in her place. Hakuno follows to find Hitori instead of Sumire; Hakuno offers her support, and the two decide to wait a little bit longer to tell the rest of STΔRLIVHT about Hitori.
He continues in Sumire's place in Chapter 1.III. Uncomfortable with the concept of wearing Sumire's STΔRLIVHT outfit and having to explain the truth about Sumire's DID to the rest of the group, he skips practice and encounters a Noise Beast. He syncs up with Sumire using the NOISZ to defeat it, though this takes its toll on them and Hitori heads home. A week later, Sumire has recovered and is back in control. |
Chapter 3
| Hitori wakes up to an extremely concerned STΔRLIVHT in Chapter 3.I, and is forced to explain the truth about himself to the group, with Hakuno's assistance. Sera and Grace take this in stride and discuss arrangements - though, unable to hear Sumire in his head, Hitori turns down the possibility of dancing with them.
Depending on the player's choices, Hakuno may opt to check up on Hitori in Chapter 3.II, as well as Rhyme if they were invited, and Hitori forgets his worries for a while. Hitori still struggles with the situation and the nature of his existence, however, and begins to worry about letting Sumire's friends, and he agrees to join STΔRLIVHT's practices in Chapter 3.IV despite his discomfort. A Noise Beast attacks, and he is unable to handle it alone. He calls out to Sumire for help, and she responds, helping him defeat it. From this point on, Hitori becomes available for normal play, and he and Sumire can use each other's styles, as well as appearing in Area Conversations. |
Chapter 4
| If enough of a bond has been built up with Hitori over the playthrough, Hakuno may ask him on a date/hangout. |
