Crane and Waterfall is a poem composed during the Devcom 2025 demo of OKU, serving as the primary example of how the game's poetry composition system works. The full text reads: "as the crane feels / as the waterfall touches / cascading and delicate." This three-stanza verse demonstrates the core loop of selecting line formats, placing collected words into slots, and producing a complete poem that can unlock sealed areas or fulfill quest objectives. It is the only complete poem documented from pre-release coverage.

The poem uses two distinct line formats. The first two stanzas follow the "as the {noun} {verb}" template, with Crane paired with Feels and Waterfall paired with Touches. The third stanza uses the "{adjective} and {adjective}" format, combining Cascading and Delicate into a closing line that balances motion with stillness. The result is a poem that moves from observation (a crane feeling, a waterfall touching) to description (cascading and delicate), creating a small narrative arc within just three lines.

What makes this poem particularly interesting is how its word choices create unexpected personification. Cranes do not "feel" in the human sense, and waterfalls do not "touch" with intention, but by assigning these verbs to natural subjects, the poem invites the reader to imagine consciousness within nature. This is the essence of OKU's creative vision: using the constraints of haiku-like composition to generate moments of genuine poetic beauty from a limited vocabulary. The demo poem was printed on a thermal printer at the Devcom booth, allowing visitors to take their compositions home as physical keepsakes, underscoring the game's emphasis on poetry as something tangible and worth preserving.
