Senri Ichinose

A quiet young man whose handsome features belie his somewhat negative personality. In the past he received cruel treatment from the grown-ups around him; he has difficulty trusting others and, as a result, is socially awkward. That part of him hasn’t changed since he hopped onboard; he rarely appears in any of the common areas, preferring to stay in his room most of the time.
He is part of Koharu's target group.
